I attended the show on Sept. 4th, under their restrictions. I recommend going for the earliest time slot of the day. I think I was one of 5 in my time-slot group. I was disappointed to see that Alice Cooper's Nightmare Castle was out of order, but I found plenty of other stuff to fill my time. The room is mostly pinball rather than mostly music-related displays.

There were a handful of historical inaccuracies, and a couple things that made me wonder what they meant (e.g., a Van Halen pinball machine?). Most pinball fans won't be bothered by those details.
