The city of Las Vegas has the most hotel rooms in the world.
Las Vegas: The City with More Hotel Rooms Than Anywhere
Las Vegas isn't just famous for casinos and shows—it's literally built more places to sleep than any other city on the planet. With approximately 150,512 hotel rooms as of 2025, Sin City has created enough beds to house the entire population of a mid-sized American city. The Strip alone accounts for about 86,462 of those rooms along just 4.5 miles of Las Vegas Boulevard.
To put that in perspective, Las Vegas can accommodate over 300,000 visitors simultaneously. That's like hosting everyone from Cincinnati, Ohio for the weekend and still having vacancies.
The Hotel Arms Race
When Las Vegas builds a hotel, they don't mess around. Fourteen of the world's 25 largest hotels sit along the Strip, creating a skyline of hospitality behemoths. The MGM Grand holds 5,044 rooms in a single building—larger than most apartment complexes. The Venetian Resort complex tops them all with 7,095 rooms, making it the second-largest hotel globally.
The only hotel bigger? The Clock Towers in Mecca, Saudi Arabia, with 10,000 rooms divided among seven buildings. But that's one mega-complex, not a whole city dedicated to temporary residents.
Why So Many Rooms?
Las Vegas welcomed 40.8 million visitors in 2023. That's more than the entire population of Canada. The city functions as a 24/7 hospitality machine, requiring massive inventory to handle everything from weekend bachelor parties to international conventions hosting 100,000+ attendees.
The business model is simple but extreme: build enough rooms to guarantee availability, then compete on price, amenities, and spectacle. If you can't find a room in Vegas on any given night, something has gone catastrophically wrong—or there's a major fight/convention in town.
The Numbers Keep Shifting
Despite its dominance, Las Vegas actually lost hotel rooms recently. In 2024, the number dropped 1.60% due to the closure of the Tropicana Hotel and the Mirage. Both properties are being redeveloped, which in Vegas-speak means "demolished and replaced with something even bigger."
Room rates keep climbing though. The average daily rate on the Strip hit $208.23 in January 2025, up 2% year-over-year. That's what happens when you have the monopoly on hosting 40 million people with nowhere else to stay in the Mojave Desert.
The reality: Las Vegas didn't accidentally become the hotel room capital of the world. It's a calculated bet that if you build enough beds in the middle of the Nevada desert and surround them with slot machines, fancy restaurants, and Celine Dion residencies, people will keep coming. So far, that bet has paid off spectacularly.
