The Space Center visit is very interesting. Go to take the tram ride first and it may take over 90 minutes. Wish can stay there a little longer before head back downtown.
There was some confusion on the meeting point for this tour. The address given is the Hilton but the actual meeting place is on the corner of the street. The other 2 people waiting with us were also unsure of where to wait.
the tour itself was some commentary as we drove around Houston and then we were dropped at NASA to make our own way around. This was fine as our tour guide explained where to go and the centre itself was very interesting. We were picked up on time and dropped back to our pick-up point. Great way to get to NASA if you don't have your own transport or just want someone else to drive.
The city tour was interesting. Although there is not too much history about Houston. NASA space centre was really interesting. However, the city tour started late therefore not enough time to see all the things inside the space centre. Perhaps it should start earlier in the morning e.g. 9.30am then it will give us more time in the space centre.
