We were there for five hours and only got sprinkled on, really. We left at 2:00, and it started pouring while we were on the bus back to the parking lot. I'm glad we left when we did!
Crowds were low, but with all the refurbs and then all the stuff down due to rain, by 11:00 the remaining rides had longer waits than I might have expected for the small number of people there. We had a great day, though!
