I try not to think of human pollution in the pool and some how injecting large chemical compounds to the water makes it all better even while I'm swimming. Just sounds horrible. Luckily we never got sick from it. No rashes or unexplained anything. Yet... Aside from that, yes, lines get brutal often, sometimes way understaffed, and sometimes a lot of jerks around, but that's just sometimes. If you show up early, grab some chairs under the canvas, hit the slides early, then get some sun and lounge in the pool/river. Can be a fantastic day most of the time.
