Two fun bits from my time on the Shuttle Launch Experience:
It has one of those big briefing videos at the beginning, where a group of thirty or so people all watch the same video introduction in one big room. The floor of said room was plated metal, but with squares arranged in a spaced out grid (they looked like maintenance panels or something). The doors open, the people flood in, and with no other cue then their mere existence, stand on the panels one person to each, as if each panel were a transporter pad or something. All the panels quickly become occupied but people keep flooding in. Everybody who comes after tries to find a square but can't. People then start to legitimately panic and fret about not having a square to stand on and what that means. Later, I went with another friend and as the doors opened, I whispered to her, "Wait. Hang back just a second. Watch." Sure enough, the exact same thing happened. People spontaneously lined up on these squares without any actual cue to do so. Theme parks as slaughterhouses indeed.
Also the first time I went with a friend (who worked on the shuttle program until recently), the ride itself was still quite new and they were still working out the kinks. We went by and it was broken, so they told us to come back later. We did and they had it up and running again. We waited in line, also waiting on more slight delays. Eventually we get to the front and get strapped into the actual ride, excited to finally experience the thing after so much anticipation. And then wait out more delays. Finally, they admit to us it's broken again and unload everybody. In short, the first time I tried to ride the SLE, the mission was scrubbed. Eventually, we went back again and rode the thing successfully, but my friend and I were very amused by the simulation's fidelity to real life.
And the guy giving you the briefing in the video at the beginning (at the time, I don't know if they've redone it) was Charlie Bolden, who's now the NASA administrator. He has a very grandpa-ly vibe to him.
