Though still in its conceptual phase, Dubai's Water Discus Underwater Hotel sure is making some waves (!). It's slated to begin construction soon and will offer all sorts of extravagances, including "a multifunctional lobby built inside an enormous swimming pool [that] shows the center of the disc"... and diving!
Apparently you can watch the reef in HD from your bed...because lifting your head that 15 degrees might really strain something.
And when you gaze long into an abyss, the abyss also gazes into you...wait, that's probably just your reflection.
Your room is on full display for all the aquatic life to see, so you can finally show that sea cucumber who's boss. And if that cucumber happens to show you who's boss, you can always pull down the curtains for complete privacy.
For the rich
You can gain access to the hotel by boat, but since those are for poor people and fishermen, take a helicopter instead.
All in all
The hotel's offering up 21 hotel rooms, a restaurant, a spa, and a special recreation area equipped with underwater scooters, jet-skis, and 3-person submersibles.
