Largest Hotels in Las Vegas
13. Mandalay Bay – 3,209 Rooms
Anchoring the south end of the Las Vegas Strip Mandalay Bay lays claim to the 5th largest convention center in North America boasting over 2,000,000 square feet of space.
In addition to thousands of hotel rooms, Mandalay Bay is also home to a sprawling 11-acre pool complex which is made up of a lazy river, 1.6 million gallon wave pool, a jogging track, and 2,700 tons of sand.
12. Flamingo – 3,460 Rooms
Originally opened in 1946 by mobster Bugsy Siegel, Flamingo is not only massive in size, but an iconic part of the Las Vegas skyline.
Obviously, the center Strip hotel has changed over the years, now offering a 93,000 square foot gaming floor, 2 distinct pool environments, and even an outdoor wildlife habitat that is home to various types of foul including flamingos.
Note that approximately 2/3 of Flamingo’s 3,460 rooms have also been recently renovated.
11. Resorts World – 3,506 Rooms
The new kid on the block aims to re-inject some life into the north end of the Las Vegas Strip.
Complete with over 40 food & beverage options, a 5.5-acre rooftop pool complex, 117,000 square feet of gaming, a 5,000-seat entertainment venue, and 70,000 square feet of retail, Resorts World packs a punch.

10. Fontainebleau Las Vegas – 3,644 Rooms (Opening Fall of 2023)
Fontainebleau has stood watch over the Strip as a stalled resort project for 15 years, but she’s finally set to open in December of 2024 as the 10th biggest hotel in Las Vegas.
The new resort will also boast a 150,000-square-foot casino, a rooftop pool deck, and over a half-million square feet of convention space.
9. Paris Las Vegas – 3,672 Rooms
Paris has ascended to become one of the biggest hotels in Las Vegas thanks to its integration of Bally’s former Jubilee Tower, which will be known as the Versailles Tower going forward.
The tower is currently undergoing $100 million in renovation work that will touch all 756 rooms and the exterior facade. Uniquely, rooms in Paris’ “new” Versailles Tower will be among the biggest standard options on the Strip, boasting 436 square feet of space.
8. Circus Circus – 3,773 Rooms
Known as one of the more “family-friendly” resorts in Las Vegas, Circus Circus offers guests access to the Splash Zone water playground complete with several water slides and a splash pad.
Parents, don’t worry. Circus Circus also offers a full adult casino including the largest collection of token-operated slot machines in Las Vegas.

7. Bellagio – 3,933 Rooms
A luxurious, center Strip resort, Bellagio opened in October of 1998 and cost $1.6 billion to construct.
In addition to its size, Bellagio is also known for its free Fountains of Bellagio performance, seasonal conservatory displays, and its 100,000+ square feet of gaming.
Another sizable amenity offered by Bellagio is the pool complex which is comprised of 5 pools, 4 whirlpools, and 50+ cabanas.

6. Caesars Palace – 3,980 Rooms
Sitting on an 85-acre plot of land, and comprised of 5 distinct hotel towers, Caesars is one of the biggest resorts in Las Vegas.
In addition to an impressive room count, Caesars Palace is also home to the”Garden of the Gods” pool complex, made up of 7 pools and swim-up blackjack.
5. Excalibur – 3,981 Rooms
A medieval castle-themed property, Excalibur opened in 1990 and cost $290 million to construct.
Excalibur also offers guests access to an impressive pool complex complete with 4 heated pools and 2 waterfalls and a sprawling 100,000 square foot casino floor.
Known as a budget-friendly resort, Excalibur delivers a strong value proposition to frugal tourists with lower table minimums, cheap restaurants, a budget-friendly buffet, and comparatively inexpensive entertainment.
4. Aria – 4,004 Rooms
Aria is the largest building in the world with LEED Gold status awarded for environmental sustainability. Aria’s expansive, 150,000-square-foot gaming floor is home to 145 table games and 1,940 slots.
Fine dining options are also plentiful at Aria, with quality options such as Herringbone, Catch, Carbone, and Jean Georges Steakhouse among others.
3. Venetian – 4,028 Rooms
Venetian ranks among the biggest hotels in Las Vegas, but the size of the property isn’t what catches your eye, rather the elaborate theming.
From her stunning exterior presence, the open-air piazza feel of St. Mark’s Square, to the cobblestone streets of the Grand Canal Shoppes, Venetian excels at transporting guests to another continent.
2. Luxor – 4,400 Rooms
No hotel in Las Vegas is more recognizable to the average Joe than Luxor. The iconic pyramid first opened its doors in 1993 and cost $375 million to construct.
Twin 22-story hotel towers were added to the property in 1998 allowing it to claim its position as the second-biggest hotel in Vegas.
Other notable amenities and things to do at Luxor include a sprawling 5-acre pool complex, HyperX eSports Arena, Titanic: The Artifact Exhibition, Bodies… The Exhibition, and Discovering King Tut’s Tomb.
Luxor is the largest building in the world to hold LEED Gold status for environmental sustainability.
1. MGM Grand – 5,044 Rooms
The biggest hotel in Vegas by Room count, MGM Grand originally opened in 1993 with a “Wizard of Oz” theme.
While that theming has slowly faded, guests are still welcomed by a 45-foot-tall bronze lion statue weighing in at 100,000 lbs.
A neat historic note about MGM Grand is that the Marina Hotel tower (which operated from 1975 to 1990) was incorporated into the resort during construction. The former Marina Hotel structure is now a part of MGM Grand’s Studio Tower (the one closest to the Strip) which has also been the beneficiary of recent renovation work.
Boasting 4 separate 30-story hotel Towers, MGM Grand is a behemoth to behold and, for now, reigns as the biggest in all of Las Vegas.
There you have it – The 13 biggest hotels in Las Vegas. Safe to say there’ll be a place to lay your head when you arrive!
