This time it was our 3rd visit to NASA in Florida. (before 1992 and 2013) The complex had better times. Especially the tours were a bit longer on the space center, there were many stops and we could get out of the bus and see some NASA ourselves. Now you just drive arround with the bus without stops and hear only "no photos, no photos etc". The vistor center had really bad food and many things are closed or beeing rebuild. Most of the attractions in the center did not change for 20 years. The only new are the 3d attractions and simulators, but this is rather a topic for Universal Studios and not NASA. I only give a good rate becuase of the Columbia which is new and makes a great impression.
