I was a little disappointed. My daughter and I showed up, paid to get in and wandered for about an hour. It was interesting but nothing mindblowing. Many of the exhibits were locked. Maybe only accessible on the guided tour... which I was never offered. When we we went to leave we found all the employees hanging out in the gift shop. Other yelpers have described it as good for kids. I didn't experience this. Most of what we saw was simply pictures on the wall and models. There were some actual flight suits and pieces of various shuttles but not much. Unless I find some special event going on I probably won't be back...
