I think Twister could hold 300 per show. When I did the control booth tour they said there was about 250 and it looks like 80% full. They also said it could run 12 shows an hour ideally but they never ran that many when she got older out of fear of breakdown. So in its prime twister could do 3600 an hour, and before it closed it ran 6 shows an hour for 1800. So it ate people alright.
