The Largest Hotels In The United States
In a city known for doing things on a grand scale, The Venetian Resort in Las Vegas takes things to a whole other level. The undisputed largest hotel in the United States weighs in with 7,092 suites in three connected towers and a comfortable winning margin of 604 rooms. This ranking counts the rooms and suites an owner or operator reports for one connected hotel at a single address, so sub-branded towers such as The Palazzo and Encore count with the parent property. MGM Resorts and Wynn Resorts figures come from their Form 10-K filings for year-end 2025 and Caesars Entertainment's from its year-end 2024 filing. The rest are from the owners' own published counts. All of them are on the Las Vegas Strip, and to spend a night in each would take over 130 years.
1. The Venetian Resort Las Vegas
The Venetian Resort scores our top position with 7,092 suites. There are 3,015 in the Venetian Tower, 1,013 in the Venezia Tower, and 3,064 in the Palazzo Tower. It opened in May 1999 on the site of the demolished Sands Hotel, and the Palazzo followed next door in December 2007. Every accommodation is a suite with a sunken living room. A $1.5 billion renovation announced in 2024 has redesigned the original tower's accommodations.
The property's most recognizable feature is its indoor Grand Canal. Complete with gondoliers, it meanders beneath a realistically painted sky past the Grand Canal Shoppes. The Sphere venue, opened in 2023, connects directly to the resort.
2. MGM Grand Las Vegas
MGM Grand Las Vegas comes in second with 6,488 guest rooms and suites, a figure that includes The Signature at MGM Grand, three non-gaming suite towers behind the main hotel. The world's largest resort when it opened in December 1993, it's located at the corner of the Strip and Tropicana Avenue.
Its most recognizable feature is the 50-ton bronze lion at the entrance. Installed in 1998, it replaced the original walk-through lion's head. The MGM Grand Garden Arena hosts boxing and concerts, and the Skylofts penthouse suites have a AAA Five Diamond rating.
3. Aria Resort and Casino
Aria comes in at 5,497 rooms and suites, a number that includes Vdara, the 57-story non-gaming, smoke-free suite hotel that shares the same block. Both opened in December 2009 as part of CityCenter, the 67-acre development between Bellagio and Park MGM.
Aria's two curved glass towers also double as an art gallery. The CityCenter Fine Art Collection includes Maya Lin's Silver River, an 84-foot cast-silver sculpture of the Colorado River suspended behind the registration desk, and works by Jenny Holzer, Nancy Rubins, and Henry Moore. A free tram links Aria to Bellagio and The Shops at Crystals.
4. Mandalay Bay
With 4,750 rooms and suites, Mandalay Bay takes in two hotels inside the building. These are the Four Seasons Hotel Las Vegas, which occupies floors 35 to 39 of the main tower, and W Las Vegas, the suite tower that opened as THEhotel in 2003, became the Delano in 2014, and completed its rebrand as a W in December 2024. The resort itself opened in March 1999 at the south end of the Strip.
Its 11-acre pool complex includes a wave pool and a lazy river, and the Shark Reef Aquarium houses more than 2,000 creatures, including sand tiger sharks and even a Komodo dragon. The Mandalay Bay Convention Center completed a $100 million upgrade in 2024, and MGM Resorts reported that December 2024 was its strongest-ever month for convention bookings.
5. Wynn Las Vegas
Wynn Las Vegas and its sister tower Encore together have 4,748 guest rooms, suites, and villas, just two shy of Mandalay Bay. Wynn opened in April 2005 on the site of the old Desert Inn, and Encore followed in December 2008. The two bronze-glass towers curve toward each other and are connected at ground level by a casino esplanade.
The resort has its own 18-hole golf course, the Wynn Golf Club, redesigned by Tom Fazio in 2019. Its other signature is the Lake of Dreams, a three-acre lake with a 40-foot waterfall used for nightly light and music shows. Unlike every MGM and Caesars resort on this list, Wynn Resorts owns the property outright rather than leasing it.
6. Luxor
With 4,397 rooms and suites, Luxor's 30-story black-glass pyramid opened in October 1993, two months before MGM Grand, with a 350-foot-tall atrium that its builders described as the largest in the world. Two stepped towers added in 1998 contain most of the rooms, but the pyramid's guests still reach their floors by inclinators, elevators that travel up the inside of the sloping walls at a 39-degree angle.
The Sky Beam at the apex, produced by 39 xenon lamps, is billed as the brightest light beam in the world and is visible from aircraft approaching Harry Reid International Airport. A 110-foot sphinx guards the entrance. Inside, the exhibits include Titanic: The Artifact Exhibition, and the Blue Man Group has performed here since 2015.
7. Excalibur
Excalibur has 3,981 rooms and suites, which puts it a single room ahead of Caesars Palace. Opened in June 1990 at the corner of the Strip and Tropicana Avenue, its white towers with red and blue conical turrets were designed to look like a medieval castle, a theme used throughout the property.
The Tournament of Kings dinner show, staged in a 900-seat arena with jousting knights on horseback, has run since the resort opened, and guests eat with their hands. A free tram connects Excalibur to Luxor and Mandalay Bay, and a pedestrian bridge crosses Tropicana Avenue to New York-New York.
8. Caesars Palace
Caesars Palace has 3,980 hotel rooms and suites and opened in August 1966. Built by Jay Sarno, the developer who went on to open Circus Circus, it's the oldest hotel in our top ten by more than two decades. Rooms here are spread across six towers, the newest being the Nobu Hotel, a 181-room hotel within the hotel that opened in 2013 with the world's largest Nobu restaurant beneath it.
The Colosseum, a 4,100-seat theater built in 2003 for Celine Dion, has since hosted residencies by Elton John, Rod Stewart, and Adele. The Forum Shops, opened in 1992, has been expanded twice since.
9. Bellagio
With 3,933 rooms and one of the most bankable names in Vegas, Bellagio opened in October 1998 on the site of the Dunes. Built at a cost widely reported at $1.6 billion, it has held the AAA Five Diamond award every year since 2001. The resort's 80-acre site fronts an eight-acre lake where more than 1,000 fountains perform choreographed shows to music.
Inside, the Conservatory and Botanical Gardens changes its displays five times a year, and the Bellagio Gallery of Fine Art mounts rotating exhibitions. The Cirque du Soleil water show, O, has played in its purpose-built theater since the resort opened.
10. Fontainebleau Las Vegas
Last but by no means least, Fontainebleau Las Vegas has 3,644 rooms and suites and is the newest hotel in the top ten. It opened in December 2023 on the north Strip after one of the longest construction sagas in Las Vegas history. Work began in 2007, stopped in 2009 when the original developer went bankrupt, and the unfinished 67-story tower stood empty for more than a decade before Jeffrey Soffer's Fontainebleau Development bought it back in 2021 with Koch Real Estate Investments and finished the $3.7 billion project.
The resort is a sister to the Fontainebleau Miami Beach, opened in 1954, and the bow-tie motif that appears throughout the interior honors that hotel's architect, Morris Lapidus, who wore one daily. It has 550,000 square feet of convention space and a six-acre pool deck and is the tallest occupiable building in Nevada. Unlike every other resort on this list, it is independently owned.
Contenders
Circus Circus, which opened in October 1968, is one property with a claim to a place on our list. Third-party sources put it at 3,767 rooms, which would place it tenth ahead of Fontainebleau, but the resort itself only says "more than 3,700." Another is Resorts World Las Vegas. Opened in June 2021, it features 3,506 rooms split among three Hilton brands in one 59-story tower. These are the Las Vegas Hilton with 1,678 rooms, the Conrad with 1,496, and Crockfords with 332.
Why Las Vegas?
It's no accident that all ten hotels on this list are in Las Vegas. Strip resorts earn more than half their revenue from rooms, restaurants, shows, and conventions, rather than gaming, and every additional room feeds those businesses. That's why operators keep adding sub-branded towers to existing properties, such as The Signature at MGM Grand and W Las Vegas at Mandalay Bay, rather than building new ones. Room counts shift as towers are added, renovated, or taken out of service. Check this list in a few years' time, and it's highly likely the order will have changed.
