Atlantis is more than just a hotel, it's an aquatic extravaganza. We'll let the numbers do the talking. This $1.5 billion dollar mega-resort is over 4.9 million square feet, features more than 1,500 rooms, 65,000 fish, and 21 restaurants on the premises, which include four of the world's top chefs, most notably Nobu Matsuhisa and Giorgio Locatelli. Still not convinced? Head to Atlantis' Aquaventure water park, where you can swim with the dolphins, river raft, or head down an 89-foot vertical drop water slide known as "The Leap of Faith."
