This is a very unsafe attraction with park supervision being little or none. There are "lifeguards" on the entry level but once you start ascending to the water slide levels, you can literally be drowned by guests misusing the provided water features.Hershey, get some lifeguards monitoring guests on the upper platforms!!
Two stranger teenage girls sprayed my 10 year old in the mouth with a contraption that resembled garden hose at close range and they followed him with it- when I asked them to stop they did it stronger. He felt completely unsafe and threatened and I had no control over the force of the water.
It looks fun from the outside, but if the rest of the rides in Hershey are run the same way. oh boy, you are no way in safe hands.
Go to the beach instead!
