We never had a problem walking up about 30 minutes prior to show time and getting in. There are definitely times when people are turned away though.Does it really get that crowded that you have to stand to find a seat? Can you just show up right before the shower and get a nosebleed seat?
IIRC - at one point they were doing 2 shows per night. Maybe at 6 and 9PM. That made it much easier to get into the second show from what I remember....
