I was at the park 3 times last week.
On Thursday there was hardly anyone there at all. My wife and i spent half of the day at the water park and everything was walk on with no waiting anywhere.. I think they even sent the flash pass guys home. The other half of the day we went to the theme park..same thing..hardly anyone inside the park. They were even shutting down our favorite restaurant JB's Smoke House and Sports Bar at 6 pm. We also noticed there were lots of concession stands and Character Cafe were closed too all before 6 pm. We only wanted to ride the roller coasters even though the park was empty all of the roller coasters were only operating 1 train so for a front seat you had to wait a 5-10 min. The dragons wing and go karts were also closed before 6 pm. I had never seen the park so empty before.
On Saturday it was just my daughter and I. We stayed in the water park most of the day and it was extremely crowded. There was a line for all of the rides in the water park. Good for the park that day. We still had fun though! Bad weather came in about 7 pm or so and shut down everything for the remainder of the night. On a positive note I found out that you don't have to get those pretzel buns on your sandwich at JB's smokehouse and sports bar.
On Sunday it was myself, my wife and my 2 kids.. Once again we did the water park for most of the day and the crowd was pretty good size until weather shut down everything for about a hr and cleared out a lot of people. After the storm passed the crowd was very light.
