We went for 1 day to Blizzard Beach back in July.
Worst.Park.Ever. We asked for our locker deposit and mug refill money back (ticket was part of the park hoppers)
Just about every ride was shut down due to water pressure issues. We rode the chair lifts up to the top. But that's about all we were able to do. We waited in line for one of the tube rides for 45 minutes only to have them turn us back within 10 people from the ride start.
