Now Even Grown-Ups Can Have a Night at the Museum

You might be getting older but that no longer means you have to grow up.

The American Museum of Natural History announced Tuesday it will soon host its first sleepover for grown-ups.

The museum has been hosting a “night at the museum” event for kids for several years, but on Aug. 1 it will hold its first event for people aged 21 and up, complete with a champagne reception and a jazz trio.

For $375—or $325 if you’re a member—a person can spend the evening from 6:30 p.m. to 9:00 a.m. roaming “through the nearly empty halls of the museum, where they might run into a herd of elephants in the Akeley Hall of African Mammals or come face to face with looming dinosaur skeletons, including a 65-million-year-old Tyrannosaurus rex,” the museum said in an announcement.

The event will also include a midnight viewing of the museum’s Dark Universe Space Show, narrated by Neil deGrasse Tyson.

“As the evening winds down,” the museum says in its announcement, “guests will be able to unroll their sleeping bags and curl up under the beloved 94-foot-long blue whale in the Milstein Hall of Ocean Life.”
