One of the underwater hotels currently under construction is the Crescent Hydropolis of Dubai. Dubai has become notorious in recent years for its fabulously modern architecture. It seems the wildest architectural dreams become reality here. The Hydropolis furthers this notion. At a cost of some $550 million, the luxury resort is being built on the Persian Gulf floor 66 feet below the surface. When completed, the project will cover 27 acres and compose of an above ground land station connected by a 1700 foot transparent train tunnel to the undersea hotel which resembles the shape of a jellyfish. The 220 suites will be bubble-shaped, with clear glass comprising both the sleeping area walls and the bathtubs. I suppose modesty must be checked at the front desk also. Anxious sea-dwellers will have to wait until 2009 before making a reservation. You may even want to have a look at some existing Dubai hotels before diving into the ocean for Hydropolis.
