Airbnb and the Paris Aquarium are holding a contest for shark-tank sleepovers

Three winners and their guests will spend the night in a submerged room

CNN  — 

Insomniacs will be counting sharks instead of sheep during an overnight stay at the Paris Aquarium in France. So say the organizers of a contest sponsored by Airbnb Ireland offering three lucky winners and their guests the chance to spend a night at the aquarium in a submerged glass room with 35 sharks as neighbors.

In addition to its fearsome inhabitants, the tank contains 3 million liters (nearly 800,000 gallons) of water. The sleepovers will take place on April 11, 12 or 13.

Interested parties are invited to apply to win through a listing on Airbnb. Applicants must be at least 18 and in good physical health. Record-setting free diver, photographer and shark enthusiast Fred Buyle will host the underwater event, and a marine biologist will be on hand to shed light on the mysterious life of sharks.

Thirty-five sharks live in the tank guests are invited to stay in.

The Paris Aquarium’s offer comes on the heels of another unique Airbnb collaboration.

In February, the Art Institute of Chicago paired up with the lodging site to offer stays in a replica of Vincent Van Gogh’s famous bedroom during its “Van Gogh’s Bedrooms” exhibit. For the Paris shark stays, messages to the judges should explain why you’re the perfect candidate and must be between 50 and 550 characters in either French, English, German, Spanish, Italian or Portuguese.

Entries in Chinese, Japanese or Korean will also be accepted, with a character limit of 300. Applicants must have an Airbnb account and apply before midnight Central European Time on April 3.

There’s no cost to enter or stay and organizers will take care of flights for winners. The transparent room sleeps two in a circular bed.

The listing mentions dinner and breakfast as well as basic amenities including linens, soap, toilet paper and shampoo. Organizers caution against viewing “Jaws,” or “Les Dents de la Mer,” before the sleepover.
