What water-related hotels are there in the world?

Dubai will build an underwater hotel that looks like a spaceship and can sleep with fish.

The hotel looks like a spaceship, and the underwater part is located at the underwater 10 meter, which is connected with another disc-shaped building on the water. The hotel has 2 1 rooms, next to the diving center and the submerged bar. A special lighting system will illuminate the plants and animals outside. In case of danger, the underwater room will be able to float

In addition, some underwater rooms allow passengers to see the fish in the sea at close range, but they can also receive sunlight.
