Luxury Hotels of World

Some hotels have accommodation underwater, such as Utter Inn in Lake Mälaren, Sweden. Hydropolis, project cancelled 2004 in Dubai, would have had suites on the bottom of the Persian Gulf, and Jules Undersea Lodge in Key Largo, Florida requires scuba diving to access its rooms.

Utter Inn
Utter Inn (Swedish) or in English, Otter Inn, is an art project by Mikael Genberg which offers underwater accommodation to the public. The facility is entered through a typical Swedish red house located on the surface of the water. The only representation of this concept is, at this point, located in Lake Mälaren near the town of Västerås in Sweden.

Hydropolis
The Hydropolis Underwater Hotel and Resort is a planned hotel, designed by Prof. Roland Dieterle which will be the world's first underwater luxury resort. It's situated 66 feet below the surface of the Persian Gulf, just off Jumeira Beach in Dubai. Reinforced by concrete and steel, its Plexiglas walls and bubble-shaped dome ceilings will enable guests to see fish and other sea creatures. It is basically divided into three sections: the land station, where guests will be welcomed; the connecting tunnel, which will transport people by train to the main area of the hotel; and the 220 suites within the submarine leisure complex. It will cover an area of 260 hectares, about the size of London's Hyde Park, and will cost an estimated £300 million. It is self-acclaimed to be a 10-star hotel and will be charging circa $5,000 per room per night.

The hotel was scheduled to open in late 2006; however, due to the engineering and environmental difficulties of constructing an underwater hotel, the project was delayed. Architects working on Hydropolis have had some difficulty selecting a suitable position for the complex, as concerns have been repeatedly raised about the displacement effect of building a 260-hectare underwater structure. If their calculations are incorrect, tides and sea levels off the coast of Dubai could be severely affected, rendering vast tracts of coast uninhabitable due to chaotic tides, flooding, unpredictable wave patterns and a high possibility of whale and other sea-mammal beaching. Disney corporation are reportedly in talks with the developers of Hydropolis to bring a fully underwater production of The Little Mermaid to the hotel's lobby.
