Laying easy on the fascinating space travel, the visitor center is an absolute bull.
Overcrowded, you make a 300 ft. Line to wait for a 3 minute tram trip to see the overwhelming Saturn V space ship (now inside a huge warehouse) with a mediocre information displays that look like they set them up a century ago, then again another 400 ft. line to get back up at the tram for the last 3 minute trip and thyr drop you off at the center… if you could go walking to the Saturn V it could be done in half the time.
They say the opening hours are until 5 pm but that’s a big fat lie, because the trams start running an hour before and you will not have access to the Space Shuttle and other areas since one or half hour before the closing time.
Of course the only open area until the last minute is the souvenir store.
If you manage to move whithin a million people, every exhibit will be so crowded that you will always see the displays over some one’s shoulder.
Bottom line, they have no idea how to care about the visitor’s experience, laying back on the facinating space program.
I cannot encourage not to go, just be prepared for an overpriced and mediocre experience.
