There are Atlantis hotels around the world, but the one in Dubai has something special. The hotel balances five star comfort with the underwater experience. Even if you don't want to pay for the $8,835 per night underwater rooms, the hotel boasts an underwater restaurant and a water-slide that safely (or so they say) catapults you into a shark-infested lagoon.
