The Biggest Hotels in Las Vegas (and the US): Which Resorts Have More Than 3,500 Rooms?

Almost every hotel in the United States with more than 3,500 rooms is located on or near the Las Vegas Strip. The MGM Grand, Aria, Bellagio, Wynn, Venetian, and a handful of other megaresorts each hold between 3,500 and more than 7,000 rooms under a single roof - a scale of hospitality that exists nowhere else on earth.

TL;DR: Las Vegas dominates the list of the largest hotels in the US. If a property has more than 3,500 rooms, there is an overwhelming chance it sits right here on Las Vegas Boulevard.

Why Las Vegas Owns This Record

The economics of Las Vegas - gaming revenue, entertainment, conventions, and non-stop tourism - made it possible to build resorts at a scale that would be financially unthinkable almost anywhere else. When a single property can host a 20,000-seat arena, a dozen restaurants, a casino floor the size of several football fields, and a luxury spa all at once, 4,000 rooms stops feeling excessive. It starts feeling necessary.

The result is a skyline unlike any other in America, and a concentration of architectural spectacle that rewards exploration from ground level - especially at night, when the neon and the LED canopies and the dancing fountains turn the whole boulevard into something cinematic.

Every US Hotel With More Than 3,500 Rooms (Ranked)

The list below reflects publicly reported room counts for major US properties. Room inventories can shift slightly due to renovations or reconfigurations, so treat these as authoritative estimates rather than live figures.

1. The Venetian Resort Las Vegas - approximately 7,092 suites. The largest hotel in the United States and one of the largest in the world. Every room is an all-suite accommodation, which makes the sheer volume even more staggering.
2. MGM Grand Las Vegas - approximately 6,852 rooms and suites. The iconic green lion at the entrance guards what was once the largest hotel on earth when it opened in 1993.
3. Aria Resort & Casino - approximately 4,004 rooms. The centerpiece of CityCenter, Aria is a showcase of contemporary architecture and one of the most technologically advanced hotels ever built.
4. Wynn Las Vegas & Encore - approximately 4,748 rooms combined across both towers. Steve Wynn's twin resorts share a property and are consistently ranked among the finest hotels in the world.
5. Bellagio Las Vegas - approximately 3,933 rooms. The fountains out front are one of the most photographed landmarks in the country. Inside, the lobby ceiling holds Dale Chihuly's famous glass sculpture - 2,000 hand-blown flowers suspended overhead.
6. Mandalay Bay Resort and Casino - approximately 3,309 rooms in the main tower, with the Four Seasons and Delano towers pushing the complex well above 3,500 total keys.
7. Caesars Palace - approximately 3,976 rooms across its multiple towers. One of the most recognizable names in Las Vegas history, Caesars has been expanding since 1966.
8. Luxor Las Vegas - approximately 4,407 rooms. The black glass pyramid and the Sphinx out front are visible from miles away - and the beam of light projected from the apex is reportedly the strongest in the world.
9. Excalibur Hotel & Casino - approximately 3,981 rooms. The medieval castle aesthetic is pure Las Vegas maximalism, and the turrets are a genuine Strip landmark.
10. Circus Circus Las Vegas - approximately 3,767 rooms. One of the oldest continuously operating hotels on the Strip, and still one of the largest.

Outside of Nevada, the list of US hotels with more than 3,500 rooms is extremely short. The only serious contenders are a small number of large convention-focused properties in Orlando and Chicago - but none approach the density or scale of what Las Vegas has built.

What It Actually Feels Like to Stand Next to These Buildings

Reading room counts is one thing. Standing at the base of the Luxor pyramid at night, or watching the Bellagio fountains choreograph to music in front of a crowd of thousands, is something entirely different. These buildings are not just large - they are designed to be experienced. The facades, the lighting, the landscaping, the scale of the porte-cochères - every detail is calibrated for impact.

That is exactly why so many visitors find that a walking tour of the Strip undersells it. The distances between these properties are deceptive. What looks like a short stroll on a map can be a 25-minute walk in 105-degree heat, and the best angles - the ones that show you the Wynn's copper tower reflected in the lagoon, or the way the Bellagio and Paris sit across from each other like a postcard - are not always visible from the sidewalk.

Seeing the Strip from inside a private limousine, with a professional photographer capturing the moments as they unfold, is a genuinely different experience. Our 1.5 Hour Las Vegas Strip Limo Tour covers the heart of the boulevard - the Bellagio fountains, the Venetian canals, Caesars, the Luxor beam - in a format that lets the scenery do the work. For guests who want to extend the journey all the way to the vintage neon of Fremont Street, the 2 Hour Strip and Fremont Tour connects both ends of Las Vegas history in a single evening. And for larger groups celebrating together, the Party Bus Tour accommodates up to 30 guests with the same all-inclusive experience.

A Note on "Largest Hotel in the US" vs. "Largest in the World"

The Venetian Resort's roughly 7,092 suites make it the largest hotel in the United States by room count. Globally, a handful of properties in Asia - particularly in Macau and Malaysia - edge it out. But the Venetian holds a distinction that raw room counts don't fully capture: it is an all-suite property at that scale, meaning every single one of those 7,000-plus accommodations is a suite with a sunken living room. That is genuinely without parallel anywhere in the world.

Fewer than a dozen US hotels have more than 3,500 rooms, and the vast majority of them are on or adjacent to the Las Vegas Strip. A small number of large convention hotels in cities like Orlando hold comparable inventories, but Las Vegas accounts for most of the properties on this list.

Is the Bellagio one of the biggest hotels in the US?

Yes. The Bellagio has approximately 3,933 rooms, placing it firmly among the largest hotels in the United States. It is also one of the most recognizable, largely because of its iconic dancing fountains on Las Vegas Boulevard.

What is the best way to see multiple large Strip hotels in one evening?

A private limousine tour is one of the most efficient and enjoyable ways to take in multiple megaresorts in a single outing. A guided tour covers the key landmarks - the Bellagio fountains, the Venetian, Caesars, the Luxor pyramid - without the heat and walking distance that make a self-guided Strip walk more taxing than expected.

Are these large Las Vegas hotels close to each other?

They appear close on a map, but the Strip is longer and the properties larger than most visitors anticipate. The walk from Mandalay Bay at the south end to the Wynn at the north end is roughly four miles. Many of the megaresorts also have very deep setbacks from the sidewalk, which adds distance. A private vehicle makes the geography much more manageable.
