Atlantis, Paradise Island, Bahamas

More like Disney World with an ocean theme than a mere resort, the Bahamas' Atlantis boasts a vast water park home to sharks, turtles, and more than 50,000 other sea animals, plus an array of water rides. That's on top of 3,000 guest rooms, 42 restaurants and bars, the biggest casino in the Caribbean, and a Mandara Spa. Three-night packages including accommodations and airport transfers start at $499 per person for stays between January 2 and February 29 when you book by December 14, 2007.
