The idea of sleeping overnight in a museum is a strangely irresistible one, having been explored in everything from The Royal Tenenbaums and From The Mixed-Up Files Of Mrs. Basil E. Frankweiler to the Night At The Museum franchise. For the most part, however, those museum all-nighters have been reserved for kids, and/or Ben Stiller. Bot not anymore: This September, the Milwaukee Public Museum will once again host its very own adult sleepover, open to anyone 21 and older who dreams of dozing off in the vaguely creepy Streets of Old Milwaukee.

Beginning Friday, September 29 at 5:30 p.m., and ending Saturday, September 30 at 9 a.m., urban campers can discover if “T.rex snores, the rattlesnake shakes into the wee hours of the morning, or if the mummies are afraid of the dark.” Adult summer camp Camp Halcyon is getting in on the fun, too, with first-floor activities like trivia scavenger hunts, board games, cocktails from Boone & Crockett, and more. Add in guided tours, curator chats, and films in the Dome Theater, and you have a doozy of a night. Oh, and it’s kid-free, and the Milwaukee Public Museum is amazing.

Tickets are $125 per person, and include admission and programming, food, two drink tickets, a late-night snack, and breakfast. Registration for (required) reservations ends Tuesday, September 19. More information can be found at
