Be you a squalling man-child or just an avid Wes Anderson fan, chances are you’ve fantasized about bunkering down in the Museum of Natural History after hours. With dinosaur bones, dioramas, Native American relics, and the Hayden Planetarium, it’s one of few places that can induce seizure-like fits of whimsy in kids and adults alike. Tonight nostalgic Gen Y-ers (is there any other kind?) revel in A Night at the Museum For Grown-Ups, an “adult” version of the popular sleepover normally reserved for wildly overprivileged children. The 21-and-up event includes a three-course dinner, wine and beer, live music and performances, access to all exhibits, guided flashlight tours, a special midnight presentation of the Dark Universe with Neil deGrasse Tyson, and breakfast to round it all off. Guests sleep on cots in the Hall of Ocean Life, beneath the 94-foot-long blue whale and likely as far away from that terrifying giant squid display as they can manage. There’s a puzzling addendum to the museum’s checklist that states “no pajamas allowed,” but guests are encouraged to go to town on sleeping bags, pillows, and change for the vending machines. Sweet dreams.
