People are talking about our SlumberCity overnights!

Since 2007, lots of happy campers have spent the night at City Museum. Here’s what a few of them have had to say about it.

“We spent the night at the City Museum’s family sleepover – What a blast! So many other children’s venues leave me on the sidelines, chatting with the other parents or reading a book and passing the time. At City Museum, I am pulling my kids into different places, instead of the other way around. I was very impressed with the staff, as well. They seem to have the right mix of keeping order and providing help and direction without imposing themselves in a way that makes you feel unwelcome.”

“Being there overnight gave us an intimate sense of the place that you might not get in the frenetic pace of the crowds during the day. We will be back!”

The cost is $50.00 per person, child or adult. Program includes:

  • Pizza dinner buffet and a breakfast buffet.
  • All-night access to City Museum, including MonstroCity, Enchanted Caves, Art City, and more!
  • Activities throughout the evening.
  • A commemorative “SlumberCity” badge you can’t get anyplace else!
  • Free parking
