We didn’t see anything and had to go back, my kids were busy all the time (10, 12 and 15). There were lots of places in the museum to focus on. We loved the various exhibitions, the history of stamps and the secrets of the postal service. The postal train with the movie was really cool. (My son liked to sit in Big Grey to deliver mail) There was a place where children and adults could pick out six stamps to start stamp collection. My kids were hooked. We didn’t even go to the second floor. The museum is free and making sure you spend time on the first floor, I find it very interesting to know about the history of stamps and how mail has been delivered over the years.
