This was our first visit. It was a little smaller than I thought it would be. However we found it very inspirational. All of the exhibits were great. My kids loved the interactive area. One or two of the interactive exhibits didn’t work and needed to be maintenanced. We understand this happens anytime a lot of people are using something frequently. The building itself was beautiful. We all learned a lot. It was also very affordable. We will probably visit again at some point.
