8 amazing underwater attractions
If you really want to "get away from it all," there's only one place for it. Outer space.
But a good second option can be found in the opposite direction -- under the sea, with only glass between you and oceans of water.
Try these attractions, usually the domain of snorkelers, divers and fish, for a pseudo-otherworldly experience.
No breath-holding required.
Jules' Undersea Lodge, Key Largo, Florida, United States
There's no front door to this hotel, which visitors enter by swimming up through a pool in the floor (compressed air keeps water from flooding the structure).
Named after French author Jules Verne, the former research lab isn't quite "Twenty Thousand Leagues Under the Sea," but rather 6.4 meters beneath the surface of the water.
Jules' caters to experienced scuba divers, with all dive gear and unlimited dives included in the room rates. But even guests who have never dived before can stay at the lodge by taking a three-hour class that allows them to dive in the company of instructors.
The hotel also offers certification training and numerous other dive courses.
Prices range from US$500-600 (meals and dive gear included) depending on the package, with discounts for groups of four or six people.

Museo Subacuatico de Arte (MUSA), Yucatan Peninsula, Mexico
The Museo Subacuatico de Arte (otherwise known as the Cancun Underwater Museum) is an underwater museum with no walls, guides or descriptive plaques.
This unique installation of sculptures by artist Jason deCaires Taylor was designed not only to encourage appreciation of the arts, but also to draw traffic away from nearby natural reefs, which were starting to bear the strain of 750,000 visitors a year.
The museum comprises more than 400 original sculptures, which also serve as artificial reefs. Many are of human figures, making the ocean floor resemble some beautifully spooky lost world, its inhabitants frozen in space and time.
MUSA is divided into two galleries, one of which is accessible to both divers and snorkelers, the others to snorkelers only. To visit, contact a Cancun dive or snorkel operation such as Delfin Diving, Aquaworld or Aqua Adventures.

Hotell Utter Inn, Västerås, Sweden
The Hotell Utter Inn (English translation: Hotel Otter Inn) is charming red house on Lake Mälaren with a sundeck -- and a single room beneath the surface of the water.

Ithaa Undersea Restaurant, Maldives
One of seven restaurants at the Conrad Maldives Rangali Island hotel, Ithaa was constructed in Singapore in 2004 and then transported to the Maldives, where it was lowered into the water.
Now located five meters below sea level, the world's first underwater restaurant serves "Maldivian-Western fusion cuisine" in a stunning all-glass setting.
Prices aren't cheap, at US$320 per person for dinner, but it's not every dining experience that can boast a panoramic view of the very sea life you might be eating.
Fun fact: The restaurant is also available for weddings.
Prices are US$55 for cocktails (includes canapés and one glass of champagne), US$195 for lunch (per person) and US$320 for dinner (includes one glass of Champagne).

World Discus Hotel, Dubai
Dubai has been ruminating about underwater hotels for a while. The hyped Hydropolis, conceived in 2006, would have been the world’s first underwater resort (and one of the most expensive), but it was never completed.
Now, however, Dubai is back on track with ambitious plans for the World Discus Hotel, an underwater hotel being designed by Deep Ocean Technology and partially funded by Swiss firm BIG InvestConsult.
This hotel won’t, in fact, be entirely below sea level. Plans call for the construction of two discs, one of which will be 10 meters beneath the water’s surface and contain the hotel’s 21 rooms.
Hotel guests needing a breather can head upstairs to the disc located five to seven meters above the waves, which will house the hotel’s lobby, restaurant and spa.
Whether it will become a reality remains to be seen. No date has yet been announced for the hotel’s opening.
