There used to be a water park in my hometown that had a bunch of slides and a wave pool. I used to go there all the time as a kid, and even went there as a senior on a trip. I went to birthday parties there, sometimes.
It closed in 2020 and never reopened because they had apparently been avoiding paying bills for years. It wasn’t just the pandemic. It was visible from the freeway, so I watched it slowly being demolished over the next couple years any time I passed by.
I haven’t found a water park that really compared to it yet. Most are either too small or part of a larger theme park, which is fine. It just seemed like the fact that it exclusively was a water park allowed it to focus more on the atmosphere and types of slides it had.
Same where I grew up, worst part was the developer bought it like two decades ago, sat on it for five ish years (logged a single dirt road), then put in paved roads/utilities and a demo house for another five with empty lots cut, and the last ten or so have built maybe four more. So it’s not even utilized, they cut down huge swaths of forest and it’s just sat most of the time.
