This was amazing! Granddaughter and I spent 3 hours there and still didn't find half the doors. It was like a giant treasure hunt. No hints so you have to find on your own but once you find the first one it gets a little easier. Highly recommend for kids maybe 11 and over.

Wow, the museum is packed full of many interesting items. We had a lot of fun looking for secret doors, autographed guitars and many others. My favorite was the hidden wine cellar. It's an unusual and welcome twist for DC. Highly recommend it!

A great outing with a child. The 70 secret doors was a winner.
