My husband and I stopped at the Space Center on our way down to Galveston, and I'm so glad we did. Tons of stuff to see and do!. The tram lines were very long, but with it being included in the price of admission, I can't complain too much. I wish we had more time to spend there, as we were not able to catch one of the movies. I'd plan on at least 4-6 hours there to see the exhibits, take the tram tour(s), and at least one movie. I Can't wait to come back the next time we visit the area agian.
