A great tour. We only had one full day in Houston so it was good to get an orientation of the city and the guide was very informative. Comfortable shuttle ride to NASA and the 4 hours they allow you there was perfect. I recommend this tour.
The city tour was most informative and very helpful. It was great to actually go on the shuttle!
We enjoyed this tour but I felt the directions on the voucher were vague as to where to meet the bus and we didn't get to spend enough time at NASA. The check-in address given is actually the Hilton Hotel and the bus pulls up on the corner out the front of the hotel. A staff member at the hotel informed us of this. It was after 10:00 am by the time we boarded the bus and lunch time when we got to NASA. We had to be back on the bus by 4:00 pm.
Not nearly enough time to see the Space Center - you could spend at least one and maybe two full days there without any trouble.
