What kind of establishment forces young kids to walk all the way up a winding flight of stairs and wait in line only to be told they're too short to ride a water slide??????? Literally every other water park or theme park has a sign showing how tall you have to be to ride a ride located at the entrance of the ride. I mean how much does it cost to put a little sign at the entrance of the water slides?? I mean we are talking about sending little kids shorter than 42inches back down the stairs crying their eyes out. Absolutely terrible. Either put up a sign or have a life guard stand at the entrance to measure kids instead of at the top. We won't be back.
