I figured the movies, as I doubt the rest of the area is busy. But doing a quick google, it appears the IMAX theater capacity is 377 seats. So I just don't see how the staffing (outside of no staffing) will be an actual issue. I could be wrong, but I feel people are complaining about something that "could" happen than what "will". Also outside of poor planning on a personal level (people tend to blame others for their lack of planning)
