Biggest Hotels in the World: Top 10

The biggest hotels in the world by guest-room count, as of October 2026, are led by Malaysia's First World Hotel with 7,351 rooms at Genting Highlands.

Room inventory, not star rating or nightly price, decides this list. A mega-hotel can house conference crowds, pilgrimage peaks or casino weekends under one roof without sending overflow guests across town. This Finepedia guide ranks ten properties by the best-supported published guest-room or key count we could verify as of October 2026. It rebuilds the ranking from official fact sheets, brand pages and recent travel press rather than copying older listicles that still quote 2018 room totals. Vegas still dominates the lower half of the chart, but the absolute crown sits in Malaysia, and Europe's largest campus remains in Moscow rather than on the Strip. For what happens inside guest rooms, see hotel room secrets you should know. For high-spend trips, try the most expensive resorts in the world and the most expensive luxury yachts. Budget-minded travellers may prefer ways smart travelers save money abroad and the best destinations for a solo traveler.

How We Ranked the Biggest Hotels

Primary metric: published guest-room or key inventory for a single hotel, or for an officially branded multi-tower complex marketed under one hotel or resort name on one contiguous campus. Floor area, gaming square footage and restaurant counts are interesting context, but they do not move a property up or down this ranking.

Rules used for this October 2026 ranking:

• Prefer the most recent official hotel, brand or operator figure (fact sheet, brand site or Guinness citation tied to that operator).
• When directories disagree, pick the newer official number and note the older claim in the entry.
• Count Venetian + Palazzo as The Venetian Resort because the property markets one all-suite inventory under that resort name.
• Count Wynn Las Vegas + Encore the same way: one continuous Wynn campus sold as a paired resort.
• Do not merge The Signature at MGM Grand into MGM Grand's 4,762-room main hotel total; Signature is a separately branded, non-gaming tower product.
• Do not merge Disney's All-Star Sports, Music and Movies resorts; they are three separately named hotels.
• Do not treat multi-brand integrated resorts as one hotel: Abraj Al Bait / The Clock Towers (Fairmont, Raffles, Swissôtel and others) and The Londoner Macao (Londoner Grand, Conrad, St. Regis and others) are honourable mentions only.
• Exclude pure apartment blocks, cruise ships and university dorms.
• No invented nightly rates.

Ranking Snapshot

Biggest Hotels at a Glance

1. First World Hotel

Origins and History

First World Hotel sits in the cool highland resort that Lim Goh Tong pioneered above Kuala Lumpur. Early towers opened in the early 2000s as a high-volume, value-focused hotel beside Genting's casino and indoor attractions. Guinness World Records recognised 6,118 rooms in 2006. The Venetian / Palazzo expansion in Las Vegas briefly took the rooms crown, then First World regained it on 20 June 2015 after adding inventory that pushed the total to 7,351 operational rooms — still the figure Resorts World Genting publishes in 2026.

Key Features

• Three towers with room types from compact standards to World Club rooms with living space.
• Bright striped facade that reads as a landmark from the highland approaches.
• Indoor links to shopping, dining, Skytropolis Indoor Theme Park and the Genting International Convention Centre.
• Express check-in kiosks historically marketed as a regional first for the brand.
• Mid-market positioning that fills rooms with domestic and regional leisure traffic rather than ultra-luxury ADRs.

Significance

No other single hotel brand currently publishes a higher verified room count. First World proves that "biggest" can mean high-throughput hill-resort hospitality rather than Strip spectacle. The property also shows how a casino-resort company can monetise altitude, cool weather and indoor attractions while selling rooms at volume prices. For journalists, meeting planners and curious travellers, it remains the benchmark whenever someone asks which hotel has the most keys on Earth — a question that still generates viral graphics with outdated numbers.

Interesting Facts

• Guinness lists the 7,351-room total as of 20 June 2015; Genting still uses that number on its First World Hotel page in 2026.
• The property previously held the world-largest title with about 6,118 rooms before the mid-2010s expansion.
• Room sizes are compact by Western suite standards — inventory scale, not suite footprint, drives the record.
• Guests stay above the heat of the Klang Valley; the highland climate is part of the product.
• The hotel is one node in a wider Resorts World Genting campus, not a freestanding city hotel.

2. The Venetian Resort

Origins and History

Sheldon Adelson's Venetian opened in 1999 on the former Sands site, importing Venice canals, Campanile cues and all-suite rooms sized well above the Strip average. The Palazzo joined in 2008 under the same resort umbrella. Older listicles often quoted Venetian alone near 4,000 rooms or a combined figure near 7,000–7,264. As of 2026 the resort's own marketing states 7,167 lavish suites spanning both towers — the figure used here.

Key Features

• Every accommodation is marketed as a suite, typically starting around 650 square feet.
• Indoor canal with gondola rides and St. Mark's-inspired public spaces.
• Large meeting inventory and shopping arcades under one roof.
• Direct adjacency to Sphere, which reshaped the east-of-Strip entertainment map after 2023.
• Dual hotel personalities: Venetian theatrical Italianate; Palazzo sleeker contemporary luxury.

Significance

Among contiguous same-brand resort complexes, The Venetian Resort is the largest all-suite campus on the Strip and second only to First World Hotel on this global rooms list. It shows how a themed mega-resort can rival a highland volume hotel when two towers share one inventory. The all-suite product also changes labour and housekeeping maths: each key is larger than a standard Strip queen room, so "7,167 rooms" understates the floor area relative to a compact mid-market tower with the same count.

Interesting Facts

• Some secondary databases still list 7,264 rooms; Finepedia prefers the resort's published 7,167 figure.
• Hyatt's late-2024 licensing deal described roughly 7,000 rooms joining World of Hyatt — consistent with the suite total.
• The property is frequently called the only all-suite resort on the Las Vegas Strip.
• Palazzo's opening was the moment many "largest hotel" lists briefly crowned Las Vegas over Genting.
• Suite living rooms and dining areas, not just bed count, define the guest product.

3. Izmailovo Hotel

Origins and History

Soviet planners built Izmailovo to house Olympic athletes and visitors in 1980. Four high-rise blocks still dominate the skyline east of central Moscow. For years English-language listicles repeated a 7,500-room figure. More recent travel round-ups and hotel summaries converge on about 5,000 rooms for the complex, which remains Europe's largest hotel campus by most 2025–2026 comparisons. Finepedia therefore ranks Izmailovo third on a ~5,000-room basis and flags the older 7,500 claim as outdated for this list.

Key Features

• Four named towers (Alpha, Beta, Vega, Gamma-Delta) on one campus.
• Mid-scale rooms aimed at tour groups, events and value city stays.
• Walking access to the colourful Izmailovo market and kremlin replica complex.
• Convention and banquet space scaled for large domestic groups.
• Separate tower branding that still reads as one Olympic-era hotel city.

Significance

Izmailovo is the clearest European answer to Asian and Las Vegas mega-hotels. It also illustrates why room counts age poorly: repeating 2018 totals without checking current complex figures overstates capacity by thousands of keys. For travellers, the practical takeaway is simpler — expect a vast, functional hotel city with tour-group energy rather than a boutique atrium, and confirm which Greek-letter tower your voucher names before you arrive with heavy luggage.

Interesting Facts

• Older Western lists (including the 2018 reference topic) often printed 7,500 rooms; treat that as historical marketing, not the 2026 ranking input.
• The Greek-letter tower names remain a quick way to navigate the campus.
• Olympic heritage is still the origin story used in Russian and foreign coverage.
• Travelnews and similar 2025 features still call it Europe's largest hotel at about 5,000 rooms.
• The complex sits near forest parkland rather than a casino strip.

4. MGM Grand Las Vegas

Origins and History

The emerald MGM Grand that opened in 1993 replaced an earlier MGM Grand on a different Strip site. Four 30-story towers created what is still often called the largest single hotel building by rooms in Las Vegas. MGM's 2026 fact sheet lists 4,762 guest rooms in the main hotel. The Signature at MGM Grand — three non-gaming towers of 576 suites each — is described on the same sheet as a distinct product and is not added into the 4,762 total for this ranking.

Key Features

• Four main towers plus SKYLOFTS and The Mansion villas for ultra-high-end stays.
• More than 170,000 square feet of gaming and a major sportsbook.
• Grand Garden Arena for concerts and combat sports.
• 6.5-acre pool complex with a seasonal lazy river.
• Restore by MGM wellness rooms with air purification and related tech.

Significance

MGM Grand is the largest single-building hotel inventory on this list and the highest-ranked MGM property when Signature is kept separate. It anchors the Tropicana corner with arena-scale entertainment that smaller luxury hotels cannot match. The resort is a case study in how a 1990s mega-casino still refreshes itself — wellness rooms, dayclub concepts and sportsbook upgrades — without giving up the raw room count that put it on every "largest hotels" list for three decades.

Interesting Facts

• The bronze lion at the entrance is repeatedly billed among the largest bronze statues in the United States.
• Joël Robuchon restaurants on property long set a fine-dining benchmark for a mega-casino hotel.
• Adding Signature's 1,728 suites would push a combined campus figure near 6,500 — Finepedia excludes that merge by rule.
• Some older lists quoted 5,000+ or 6,700+ when Signature was bundled; always check which towers are included.
• Palm Tree Beach Club debuted in 2025 as a major pool-dayclub refresh.

5. Wynn Las Vegas & Encore

Origins and History

Steve Wynn's post-Mirage flagship opened in 2005 with a bronze curved tower and a landscaped Strip frontage that rejected cartoon theming. Encore followed in 2008 as a sister tower with its own lobby energy but shared campus services. Corporate and resort materials have long treated the paired towers as a 4,748-room luxury complex — the combined figure used here.

Key Features

• High average room quality and suite mix relative to most volume hotels on this list.
• Wynn and Encore atriums, parasol ceilings and water shows as signature public theatre.
• On-site golf and Ferrari-Maserati dealership heritage in earlier marketing eras.
• Dense fine-dining and nightclub roster aimed at high spenders.
• Continuous pedestrian campus between the two towers.

Significance

Wynn + Encore proves a luxury ADR strategy can still crack the global top five by rooms when two towers are counted as one resort. It sits just below MGM Grand's main-hotel total while aiming at a different guest spend band. Where First World sells altitude and volume, Wynn sells finish, landscaping and dining density — yet both appear in the same rooms conversation because the key counts are in the same league once Encore is included.

Interesting Facts

• Encore alone is often cited around 2,000 rooms within the 4,748 combined total.
• The resort is regularly named on "best of Strip" luxury lists despite its mega scale.
• Unlike Venetian, Wynn's towers are not all-suite; the luxury pitch is finish and service.
• Golf access on the Strip side remains a rare amenity among the largest hotels.
• The 4,748 figure has been stable in corporate profiles for years.

6. Barkhatnye Sezony

Origins and History

Barkhatnye Sezony ("Velvet Seasons") was developed as a city-hotel to support Sochi's Olympic and post-Olympic tourism. The official site calls it Russia's largest hotel complex and one of the five largest hotels in the world, stating a resource of 4,688 rooms and capacity for about 10,000 guests. Three quarters — Yekaterininsky, Semeynyy and Sportivny — spread along the coast near the Olympic Park.

Key Features

• Apartment-style and hotel rooms across three named quarters.
• Beachfront with operator claims of Blue Flag environmental recognition.
• On-site dining, shops, kids' rooms, gym and health centre for long stays.
• Event history tied to Olympics, Formula 1 and other Sochi spectacles.
• Walkable access toward Olympic Park attractions and the Black Sea promenade.

Significance

Outside Las Vegas and Genting, Barkhatnye Sezony is one of the few post-2010 projects that still cracks a global rooms top ten. It is a resort-city hybrid: more horizontal campus than a single glass slab. Olympic host cities often leave behind awkward white elephants; this complex instead pivoted into a year-round Black Sea product with beach access and quarter-based orientation that still houses thousands of keys each night.

Interesting Facts

• The operator markets "city-hotel" living rather than a classic atrium tower.
• About two million tourists are claimed since opening in operator copy.
• Room count is precise (4,688) on the official English about page — stronger than many secondary blogs.
• Quarters differ in coastline position (first vs second line from the sea).
• It is easy to confuse with smaller Sochi hotels; the three-quarter layout is the giveaway.

7. Luxor Las Vegas

Origins and History

Luxor opened in 1993 as an Egyptian-themed pyramid casino hotel and added twin towers in 1998. The black-glass pyramid and nighttime sky beam made it one of the Strip's most recognisable silhouettes. MGM's 2026 fact sheet rounds inventory to 4,400 guest rooms (some older databases list 4,407). Pyramid-tower rooms were heavily remodelled in 2021 with Moroccan and North African colour cues.

Key Features

• Pyramid atrium with inclined elevators ("inclinators") in the original building.
• Twin tower wings that hold a large share of the room count.
• Casino floor exceeding 120,000 square feet plus BetMGM sportsbook.
• Attractions such as Titanic and Bodies exhibitions alongside Blue Man Group.
• Sky bridge retail link toward Mandalay Bay via Mandalay Place.

Significance

Luxor is the highest-ranked pure themed pyramid hotel and the second MGM Strip giant on this list after MGM Grand. It shows 1990s theming still supporting four-thousand-plus keys in 2026. The pyramid is also a lesson in renovation economics: operators can refresh thousands of rooms in phases inside an unforgettable shell rather than demolishing a landmark that still photographs well from the air and the freeway.

Interesting Facts

• Original construction cost is listed around $375 million on the fact sheet — modest versus later Wynn-era projects.
• The sky beam has long been marketed among the strongest light beams of its type.
• Green Key eco-rating (four keys) appears on current MGM materials.
• Room renovations in 2021 refreshed more than 1,700 pyramid rooms.
• Excalibur and Mandalay Bay sit on the same south-Strip MGM cluster.

8. Ambassador City Jomtien

Origins and History

Ambassador City Jomtien grew as a sprawling beach resort on Thailand's eastern seaboard, aimed at groups, conventions and long leisure stays. Unlike a single Las Vegas slab, it spreads rooms across themed wings on a large coastal plot. Trade directories such as Travel Weekly consistently list about 4,210 rooms; the hotel's own marketing often softens that to "over 4,000" rooms and suites.

Key Features

• Multiple wings with different design personalities on one campus.
• Direct beach access and a resort layout that can feel like a small town.
• Substantial meeting and banquet inventory for regional corporate groups.
• On-site dining and leisure facilities that reduce the need to leave the property.
• Mid-market pricing historically attractive to large tour operators.

Significance

Ambassador City is the only Southeast Asian beach mega-hotel on this top ten besides First World Hotel's highland model. It keeps Pattaya on global "most rooms" maps even as Macau and the Gulf add newer integrated resorts. For group organisers, the wing layout can be an advantage: large cohorts can be housed on one campus with beach access without relying on a single elevator bank in a 40-storey shaft.

Interesting Facts

• Wing-based planning means walking times between rooms and beach can vary widely.
• Some lifestyle blogs still reprint 4,219 or other near-matches; 4,210 is the stable directory figure.
• The campus scale can surprise guests expecting a single high-rise.
• Jomtien is quieter than central Pattaya walking streets, which shapes the stay.
• It remains a staple of older "world's largest hotels" lists for good reason: the room count still clears 4,000.

9. Aria Resort & Casino

Origins and History

Aria opened in 2009 as the hotel centrepiece of CityCenter, the large mixed-use project between Bellagio and Monte Carlo (now Park MGM). It traded Egyptian pyramids and medieval castles for glass curtain walls, automated room features and a denser luxury restaurant set. Room count has hovered at 4,004 in older announcements and about 4,002 on newer fact sheets; Finepedia uses 4,002 as the latest operator figure.

Key Features

• Modern rooms with strong tech and design emphasis versus 1990s theme hotels.
• Casino and entertainment aimed at a premium Strip guest.
• Pool and spa facilities scaled for a four-thousand-room house.
• Walking links into Crystals retail and the wider CityCenter plaza.
• Meeting space competitive with older mega-resorts despite a later vintage.

Significance

Aria is the newest Las Vegas entry in this top ten and proof that a 2009 contemporary resort still ranks among the world's largest by keys without relying on 1990s theming. CityCenter's mixed-use bet — hotel, condo, retail and public art — also means Aria guests live next to a denser urban fabric than the south-Strip castle-and-pyramid cluster, even though the room count is in the same four-thousand band.

Interesting Facts

• CityCenter's construction was among the most expensive U.S. privately funded projects of its era.
• A one- or two-room difference between fact-sheet editions is normal; ranking position is stable either way.
• Aria often competes for awards with Bellagio and Wynn despite similar mega scale.
• The hotel's glass twin-oval silhouette is a CityCenter landmark in daylight photos.
• Guests sometimes confuse Aria's inventory with Vdara's non-gaming tower next door — Vdara is separate.

10. Excalibur Hotel and Casino

Origins and History

Excalibur opened in 1990 as a castle-themed mega-hotel aimed at families and value seekers, with turrets visible from the interstate approaches. It belongs to the same MGM south-Strip cluster as Luxor and Mandalay Bay. At 3,981 rooms it sits just under the 4,000-key line but still earns a top-ten slot once multi-brand IRs and three-resort Disney campuses are excluded under our rules.

Key Features

• Two main hotel towers inside a castle facade.
• Casino, restaurants and the long-running Tournament of Kings horse-dinner show.
• Pedestrian connections toward Luxor and the Mandalay Place bridge network.
• Mid-market rooms that keep occupancy filled with tour and family segments.
• Iconic red-and-blue exterior lighting visible in Strip skyline photos.

Significance

Excalibur closes the list as the classic early-1990s volume hotel: huge by global standards, modest by today's suite-luxury ADR goals, and still operating thousands of keys every night. It is also a reminder that "biggest hotels" lists are not luxury rankings. A castle with nearly 4,000 rooms can out-key many five-star icons that never tried to win on inventory.

Interesting Facts

• It opened before Luxor (1993) and the current MGM Grand (1993), anchoring south-Strip theming early.
• Room counts have stayed near 3,981 in MGM historical disclosures for many years.
• The property is often cheaper than Aria or Wynn while sharing the same parent company.
• Castle theming remains polarising — guests either love or joke about it — but the inventory is real.
• Together with Luxor and Mandalay Bay, it forms a walkable MGM "triangle" of mega-hotels.

Honourable Mentions and Exclusions

Rooms Versus Footprint and Opening Era

Scale and luxury are not the same axis. Wynn's room total nearly matches MGM Grand's, yet the guest experience and price bands differ. First World's record is about throughput in the highlands. Izmailovo's Olympic slabs and Barkhatnye Sezony's quarters show how host cities still solve mass accommodation with hotel-cities rather than single atriums. If you care more about calm scenery than key counts, Finepedia's guide to the most relaxing destinations to visit is a better planning companion than any rooms leaderboard.

Frequently Asked Questions

What is the biggest hotel in the world by number of rooms in 2026?

First World Hotel at Resorts World Genting in Malaysia. Resorts World Genting and Guinness World Records both cite 7,351 rooms, and that figure still appears on the brand's hotel page as of October 2026.

Is The Venetian larger than MGM Grand?

Yes on a resort-complex basis. The Venetian Resort's published suite total across Venetian and Palazzo is 7,167. MGM Grand's main hotel fact sheet lists 4,762 rooms. MGM Grand remains among the largest single hotel buildings; Venetian wins when both of its branded towers are counted together.

Why is Izmailovo not listed with 7,500 rooms anymore?

Many older English listicles used 7,500. Recent travel summaries and complex descriptions more often cite about 5,000 rooms for the four-tower campus. Finepedia ranks on the newer consensus and notes the outdated figure so readers are not misled.

Do Wynn and Encore count as one hotel?

For this list, yes. They share one contiguous campus and are marketed as a paired Wynn Las Vegas & Encore resort with a long-published combined total of 4,748 rooms. That matches how Finepedia treats Venetian + Palazzo.

Why were Mecca's Clock Towers left out of the Top 10?

The Clock Towers complex holds well over 6,000 hotel rooms, but they are split among separately branded hotels such as Fairmont, Raffles and Swissôtel. Our rule ranks one hotel brand or one officially named multi-tower hotel campus, not an entire multi-brand skyline.

Is Disney's All-Star Resorts among the biggest hotels?

Combined, the Sports, Music and Movies resorts historically exceed 5,000 rooms, but they are three separately named hotels. Under Finepedia's rules they are an honourable mention, not a single ranked property.

Which Las Vegas hotel has the most rooms in one building?

MGM Grand's main hotel, with 4,762 rooms in four towers on one hotel footprint, is the usual answer. Venetian / Palazzo and Wynn / Encore are larger only when sister towers are combined under one resort brand.

Conclusion

As of October 2026, the biggest hotels in the world by verified guest-room count still start in the Malaysian highlands: First World Hotel's 7,351 rooms lead The Venetian Resort's 7,167 suites. Olympic-era Izmailovo, MGM Grand, Wynn & Encore, Sochi's Barkhatnye Sezony and the south-Strip theme giants fill out a top ten that mixes volume tourism, casino megastructures and coastal hotel-cities. Multi-brand integrated resorts in Mecca and Macau can look larger on a skyline photo, yet they fail a one-brand test that keeps this list comparable year to year. Room counts move when towers open, wings close for renovation or brands publish cleaner fact sheets — so any "world's largest" claim should cite a date and a source, not a viral graphic from 2018. Travellers comparing stays should still weigh location, room size and total trip cost; the biggest hotels win on capacity, not automatically on comfort.
