NEW YORK (AP) — If you’re not afraid of things that go bump in the night, an adults-only sleepover at the American Museum of Natural History may be for you.

The New York City museum will have its first-ever sleepover adventure for adults 21 years old and up on Aug. 1.

It’s a far cry from the kiddie version.

For one thing, the charge is $325 for museum members and $375 for non-members.

A Champagne reception, music and a three-course dinner are on tap.

Then it’s off to explore the museum’s enormous dinosaur skeletons and African mammals. There’s also flashlight tour of the darkened fossil halls.

Participants will unroll their sleeping bags under the popular 94-foot-long blue whale.

The nocturnal adventure will run from 6:30 p.m. to 9 a.m.
