The short answer: the largest hotel in the world is the First World Hotel at Resorts World Genting, Malaysia, with 7,351 rooms and a standing Guinness record. Behind it sit the Las Vegas heavyweights, led by The Venetian Resort at 7,117 rooms (the largest in the US), then MGM Grand, Wynn with Encore, Luxor and Mandalay Bay. A points note up top: several of these book through Marriott Bonvoy.

How we ranked and verified this
We rank strictly by total room count, counting connected towers operated and marketed as one resort as a single hotel, the Venetian with the Palazzo, Wynn with Encore. Figures come from each property's current information, Guinness World Records and established Las Vegas room-count trackers. The biggest honest trap on this topic is stale and complex-versus-hotel numbers: the Londoner Macao was cut to roughly 2,405 rooms in a 2024 luxury rebrand, and the often-quoted Mecca clock-tower hotels and Moscow's Izmailovo are multi-tower complexes rather than a single property. Where a number is disputed, we say so instead of inflating the list.
The ranked list
1
Genting Highlands, Malaysia
First World Hotel — Resorts World Genting
7,351 rooms · Guinness world's largest hotel
Why it tops the list: with 7,351 rooms across two towers, First World Hotel is the largest hotel on earth and has held the Guinness title since reclaiming it in 2015. It opened in 2006 with 6,118 rooms, briefly lost the crown to the expanding Venetian in 2008, then surged back when its second tower was finished. The rooms break down as 3,164 standard, 2,922 luxury, 649 luxury triple, 480 superior luxury and 136 World Club, and the hotel plugs straight into the Resorts World Genting complex, with shopping, theme parks and Malaysia's only legal casino floor about an hour north of Kuala Lumpur.
Honest note: this is volume luxury, not boutique calm. First World is a value-priced mega-hotel built for sheer throughput, so go for the record-breaking scale and the Genting complex, not for intimacy or design.

Las Vegas, United States
The Venetian Resort (Venetian & Palazzo)
7,117 rooms · largest hotel in the US
Why it's here: counting its connected Venetian and Palazzo towers, The Venetian Resort runs 7,117 all-suite rooms, making it the largest hotel in the United States and the world's second largest. It briefly held the global title after a 2008 expansion before First World retook it. Every room is a suite, which is why the Venetian markets itself on scale and space at once rather than sheer headcount alone.
For points travelers: the Venetian sits outside the big three chains and runs its own Venetian Rewards program, so this is a cash-or-own-currency stay rather than a Bonvoy, Hilton or Hyatt redemption.

Las Vegas, United States
MGM Grand
5,044 rooms · bookable on Marriott Bonvoy
Why it's here: the emerald-green MGM Grand holds 5,044 rooms, long among the largest single hotels in the country, anchoring the south Strip with an arena, a pool complex and a deep roster of restaurants. For a points collector it is the most useful giant on this list: as part of the MGM Collection with Marriott Bonvoy, you can earn and redeem Bonvoy points, pick up Elite Night Credits and transfer points two ways with MGM Rewards.

Las Vegas, United States
Wynn Las Vegas & Encore
4,748 rooms · the most luxurious of the giants
Why it's here: the twin Wynn and Encore towers combine for 4,748 rooms (2,716 at Wynn, 2,034 at Encore) and are comfortably the most upscale entries on this list, the rare mega-hotels that hold Forbes Five-Star ratings. Scale here comes wrapped in genuine luxury, with the strongest dining, spa and pool offering among the Strip's biggest resorts.
For points travelers: Wynn runs its own Wynn Rewards rather than a major chain program, so the value here is in the on-property experience rather than transferable points.

Las Vegas, United States
Luxor
4,407 rooms · bookable on Marriott Bonvoy
Why it's here: the unmistakable black-glass pyramid holds 4,407 rooms, with its "inclinator" elevators that travel at an angle up the pyramid's slope. It is one of the Strip's value giants, a budget-friendly mega-hotel with a famous sky beam and a busy entertainment line-up. Like its MGM siblings, it sits in the MGM Collection with Marriott Bonvoy, so points and Elite Night Credits apply.
Honest note: Luxor trades on scale and price, not polish; the pyramid rooms in particular are dated compared with the Strip's newer towers, so manage expectations and book the renovated tower rooms if design matters.

Las Vegas, United States
Mandalay Bay
4,337 rooms · bookable on Marriott Bonvoy
Why it's here: Mandalay Bay rounds out the list with 4,337 rooms, a count that includes its in-house Delano and Four Seasons towers, plus a convention centre, a sand-and-wave beach pool and the Shark Reef aquarium. It anchors the far south Strip and leans into groups and conventions more than nightlife. As an MGM property it is part of the MGM Collection with Marriott Bonvoy, so Bonvoy points and elite credits work here too.

What counts as the "largest" hotel
The reason largest-hotel lists disagree is that they quietly answer different questions. Count a single building and MGM Grand's main tower leads many US tallies; count connected towers run as one resort, as we do, and the Venetian-Palazzo and Wynn-Encore jump up. Count an entire multi-tower complex and you can reach the headline figures quoted for Mecca's clock-tower hotels or Moscow's Izmailovo, built to roughly 7,500 rooms across four towers for the 1980 Olympics, but those are not one hotel in the way Guinness means it.
Two figures move the most. The Londoner Macao was widely listed near 4,000 to 6,000 rooms before a 2024 luxury rebrand cut it to about 2,405, which knocks it off any current top list, a reminder that these counts shift. And Guinness's own recognition of First World as the single largest hotel is the cleanest anchor there is, which is why it sits at the top here while bigger-sounding complexes do not.
Frequently asked questions
- What is the largest hotel in the world?
- First World Hotel at Resorts World Genting in Malaysia, with 7,351 rooms across two towers. Guinness World Records recognizes it as the world's largest hotel, a title it reclaimed in 2015 when its second tower opened, and no single hotel has surpassed it since.
- What is the largest hotel in Las Vegas and the United States?
- The Venetian Resort, counting its connected Venetian and Palazzo towers, with 7,117 rooms; it is the largest hotel in the United States and second largest in the world. MGM Grand follows with 5,044 rooms, then Wynn Las Vegas with Encore at 4,748, Luxor at 4,407 and Mandalay Bay at 4,337.
- How many rooms does First World Hotel have?
- 7,351 rooms in total, split into 3,164 standard rooms, 2,922 luxury rooms, 649 luxury triple rooms, 480 superior luxury rooms and 136 World Club rooms across two towers. It opened in 2006 with 6,118 rooms and reached its current total when the second tower was completed in 2015.
- Can you book the world's largest hotels with points?
- Several, yes. MGM Grand, Mandalay Bay and Luxor belong to the MGM Collection with Marriott Bonvoy, so Bonvoy members can earn and redeem points and Elite Night Credits, with two-way points transfer to MGM Rewards. The Venetian runs its own Venetian Rewards program, and First World books through Resorts World Genting directly, outside the major chain programs.
- Isn't the Londoner Macao or a Mecca tower bigger?
- Not as a single hotel today. The Londoner Macao was cut to about 2,405 rooms in a 2024 luxury rebrand, so older 6,000-room figures are outdated. Mecca's clock-tower hotels and Moscow's Izmailovo, built to roughly 7,500 rooms across four towers, are usually counted as multiple towers or properties rather than one hotel.
- What counts as a single hotel in this ranking?
- We count connected towers run and marketed as one property as a single hotel, which is why the Venetian and Palazzo, and Wynn and Encore, each appear as one entry. This follows how the resorts present themselves and how Guinness recognizes First World as the single largest hotel rather than the broader, multi-tower complexes in Mecca or Moscow.
