We did the water park for the firs time last year and it chewed up a lot of time. Yes they have a wave pool, but they only let X number of people in at once. so we waited and waited and waited - about an hour, for our turn. Incredibly crowded, but it's still new so maybe that was it? dunno
It was a great water section, but I was shocked at how much time it ate up.
Web site has the rides listed so you can see what they have. My kids don't do fast, but they also like the kiddie rides still so there is always plenty for us to do. Last year we bought AP for Dutch Wonderland but this year I felt they had outgrown so we bought AP for Hershey.
Food is outrageous. One s'more - exactly like you would make at home, goes for about $3.75! They don't allow food in the park, but guest services will hold a cooler for you if you have medical reasons (my youngest has severe food allergies) which is better than going all the way back to the car.
