Out of this world... :- Very impressive, a must visit if you are ever in Houston.
Our guide on the city tour did an excellent job - entertaining, good volume, and easy to hear and understand. NASA was an amazing place to visit and ranks right up there with our visits to Cape Canaveral and Sky City outside of Moscow. Children ages 10 and up can really appreciate it.
AMAZING!! The tour started out with a tour of Downtown Houston, and it's surrounding area for 90 minutes. Next, we were taken to the space center...which was the best part of the whole tour! I learned so much from the center, and would recommend this tour for all ages.
