I stand by my original recommendation. Theres a 16 minute history video and some history things, two bus tours and a self guided tour through the 747 and mock shuttle.
The two bus tours one takes you to a walk through of the iss training center and the other a walk through of the training control center and both drop you off at the Apollo V center.
The “level 9” tour promises to show more stuff but its $179 a person.
