While the American Museum of Natural History has been hosting Night at the Museum sleepovers for kids, there's never been an adult-only one. Ever. Until now. They've just announced their first sleepover for grown-ups, which will take place on Friday, August 1st.

"A limited number of 21-years-and-up guests will be able to enjoy a more sophisticated version of the popular event at A Night at the Museum for Grown-Ups, which will feature special guided tours, food, music, drinks, and behind-the-scenes access. The event will last from 6:30 p.m. until 9 a.m. the next morning."

The cost is $375 per person ($325 if you're a member), and you can learn more here (registration is now open). This is what we know so far:

  • They're capping the number of people at 150.
  • The overnight adventure will begin with a champagne reception and music (courtesy of the 12th Night Jazz trio) in the Theodore Roosevelt Memorial Hall.
  • A three-course dinner will be served.
  • Explorers can roam through the nearly empty halls of the Museum (including the spiders). There will also be a flashlight tour.
  • Participants will be invited to attend a special presentation in The Power of Poison exhibition with Curator Mark Siddall.
  • There will be a midnight viewing of the Dark Universe Space Show, narrated by Neil deGrasse Tyson.
  • Participants will also be invited to "enjoy wild creatures up close during a live animal demonstration in the Kaufmann Theater"!
  • You will sleep in your sleeping bag... under the big blue (clean) whale! When you wake up there will be a breakfast snack.
  • There will also be charging stations and tea service.
