Snoozeum Information

A unique overnight experience for your family or group of friends—now with more options!

Science Snoozeums begin at 5:30 p.m. and go until 8:30 a.m. the following morning. New this year, we are including next-day Museum Entry for each ticket holder. Your group can experience the Museum at your own pace throughout the evening and participate in Build-n-Play activities. A Snoozeum patch is available for every participant and guests can complete our Great MSI Scavenger hunt to earn an additional patch.
