Finally went yesterday, on Saturday. I had no choice but to get a flash pass if I wanted to get on all the rides, which that alone was a 50 minute wait. The park was really crowded. Lines were long everywhere. Rides were constantly breaking down. If you came in after 12pm, and you were in the regular line, you must of have been absolutely miserable. Not only were lines moving slow, but they would alternate between the flash pass line and the regular line.
I can't believe i'm going to say this, but summer time with no capacity limit, had faster lines than covid at 15% capacity. If you plan to go on a Saturday, except summer experience. About 1-2hr wait for Fully Throttle, West Coast racers, Goliath, and Twisted Colossus. Tatsu probably 30min-1hr. The flash pass line for Twisted Colossus and Full Throttle was about 20-30min.
