The First World Hotel, a high-altitude resort just northeast of Kuala Lumpur, has 7,351 rooms, which officially crowns it the World's Biggest Hotel.
But it's not just the number of rooms that puts First World on the map. The hotel's attractions make the resort a totally self-contained vacation-worthy destination.
Firstly, the views of the Genting Highlands are incredible. Here fog rolls and lifts every morning, and the buildings themselves sport a variety of wild colors, forming a rainbow between mountains and valleys.
The First World Hotel also has a 500,000-square-foot theme park, a shopping mall, and a gondola lift system that connects the property to other nearby hotels (there are five more connected to First World Plaza).
If the theme park isn't quite your scene, the hotel also has a cineplex showing new releases, a 28-lane bowling alley (glow bowling!), a Ripley's Believe It or Not! Showcase, and a "Haunted Adventure" walk.
There is another property looking to throw First World off its throne: If the ambitious Abraj Kudai is finished in Mecca, there would be a new record holder. The property planes on having more than 10,000 rooms and 70 restaurants—read about it here.
