Stay overnight in the Museum of Science and Industry, Chicago! Enjoy a rare chance to explore the Museum after everyone else has gone home.

Join us overnight for a new and improved Snoozeum experience! Spend the evening exploring the Museum, take part in a scavenger hunt and other science activities, take a Coal Mine or U-505 tour, catch a big-screen adventure in the Giant Dome Theater, then curl up next to an iconic exhibit. The Museum is yours for the night!

New Snoozeum options

Snoozeums now include next-day Museum Entry, so you can follow up your overnight with a day of exploration. Also new: three registration levels (two for large groups) allow you to customize your Snoozeum with reservations, add-ons like T-shirts, and even VIP treatment!


Registration starts at $85 per person ($75 for MSI members) with options to customize your event with additional features. Learn more about these options below.
