There’s no more perfect setting for dreams of flight than the Udvar-Hazy Center in Chantilly, Virginia. Its two huge hangars—the Boeing Aviation Hangar and the James S. McDonnell Space Hangar—display thousands of aviation and space artifacts, including a Lockheed SR-71 Blackbird, a Concorde, and the space shuttle Discovery. Sleepover guests are on a mission to explore the whole world of flight, from its pioneering days through the era of commercial aviation to the excitement of today’s space program. (Be on the lookout for aliens, too!)

Smithsonian Sleepovers at the Steven F. Udvar-Hazy Center are presented by Smithsonian Associates. Tickets cost $135. Tickets for Smithsonian Associates members cost $120. Learn more and buy tickets on the Smithsonian Sleepovers website
