Great tour of the city's architecture and history, and the included ticket and ride to the space center is well worth it. The space center is FANATASTIC! Definitely do the tram tour I did the training center tour, though I'm sure both are really cool. Saw a talk by a former astronaut on the Discovery missions, and many other things. Despite knowing a lot about space and the program, I definitely learned some things and thoroughly enjoyed it.
the both tours were really good and inforsemative . the directions for the pick up point were a bit confusing but otherwise a great day and value for money
i was told that this tour would finish back at houston at 3.45, but in fact it was not due to leave NASA till 4.15! I was mis sold this tour and had to leave early because i had a flight to catch. really bad sales experience - please check call recording.
