The 10 Largest Hotels in Las Vegas by Room Count

The Scale of the Strip: Inside the Largest Hotels Dominating America’s Horizon

When you look at the sheer concentration of architectural ambition on the Las Vegas Strip, the numbers start to blur. Yet, according to data compiled by World Atlas, one colossal property stands firmly above the rest. The Venetian Resort claims the crown as the largest hotel in the United States, weighing in with an astonishing 7,092 suites spread across three connected towers.

That gives it a comfortable winning margin of 604 rooms over its nearest competitor. When measuring properties this vast, industry analysts count every room and suite reported by an owner or operator for a single connected hotel at a single address. That means sub-branded towers like The Palazzo and Encore are tallied right alongside their parent properties, creating mega-complexes that function like self-contained cities.

How the Top Ten Stack Up

The numbers behind these hospitality giants reveal just how aggressively operators compete for sheer capacity. MGM Resorts and Wynn Resorts figures draw directly from their Form 10-K filings for year-end 2025, while Caesars Entertainment relies on its year-end 2024 filing. Every other property on the list pulls from the owners’ own published counts.

Right behind the Venetian sits the MGM Grand Las Vegas, housing 6,488 guest rooms and suites—a total that includes The Signature at MGM Grand, its three non-gaming suite towers tucked just behind the main building. Down the boulevard, Aria Resort and Casino comes in at 5,497 rooms and suites, a figure incorporating Vdara, the 57-story non-gaming, smoke-free suite hotel sharing that exact block.

Mandalay Bay follows with 4,750 rooms, encompassing both the Four Seasons Hotel Las Vegas on floors 35 through 39 and the W Las Vegas suite tower, which completed its official rebrand in December 2024. Just two rooms shy of that mark stands Wynn Las Vegas and its sister tower Encore, combining for 4,748 guest rooms, suites, and villas.

Rounding out the upper tiers are properties deeply woven into the modern history of the Strip. The iconic black-glass pyramid of the Luxor offers 4,397 rooms, while Excalibur holds 3,981 rooms—putting it a single room ahead of Caesars Palace, which sits at 3,980 rooms after opening way back in August 1966. The Bellagio commands 3,933 rooms behind its famous eight-acre lake, and the newest entrant to the upper echelon, Fontainebleau Las Vegas, brings 3,644 rooms and suites to the north Strip following a decades-long construction saga that finally concluded with its December 2023 opening.

Why Las Vegas Holds Every Single Spot

It is no accident that all ten of the largest hotels in the United States sit squarely in Las Vegas. Strip resorts generate more than half of their overall revenue from rooms, restaurants, shows, and conventions rather than traditional gaming. Every additional guest room directly feeds those secondary businesses.

That economic reality explains why operators continue adding sub-branded towers to existing properties rather than starting from scratch on entirely new parcels of land. Because room counts constantly shift as towers undergo massive multi-million dollar renovations or temporary closures, this ranking is a moving target. Check these counts in a few years, and the hierarchy of American hospitality will undoubtedly look entirely different.
