The listing describes the underwater room as "unlike anything ever built" and "a peaceful enclosure with a large cylindrical bed and breathtaking, immersive views of your new sharp-toothed friends." As you can see in the listing's photos, the shark tank bedroom is only big enough to fit a circular bed and a few other items like a nightstand, but you'll also have access to a bathroom and will be given a meal to eat while watching the sharks. Additionally, you'll be welcomed by the aquarium's shark enthusiast, Fred Buyle, who will introduce you to your friendly hosts for the night by jumping in and dancing with them.
However, staying in the shark tank will come with some important ground rules: no selfies after dark (sharks are sensitive to light), no sleepwalking or night swimming, no diving, and the listing strongly advises that you keep your heads and feet in the bedroom at all times. Oh, and you might want to avoid watching Jaws before you try sleeping there, although, you can always lull yourself to sleep by counting the sharks, right?
