I'll say right up front that I don't recommend the Pumphouse. It's very expensive. It was $246 for two days for three of us. This is a fairly low end water park in the middle of nowhere (4 slides, a small surfing pool, hot tubs, lazy river and a few other nic-knacks), not Disney World! In addition, you're going to get nickel-and-dimed. Lockers are $9 a day (more on this later), food is expensive and bland (chicken nuggets, burgers, and Fries) or you can go to an upscale cart called, (this is really what it's called) Miso Hungry, and pay $40 for 3 bowls of Ramen. My beer was $10. I looked into staying at the lodge overnight but that was over $400 once all the taxes and fees were added, appropriate for Boston, not Jay. We ended up at a $100 a night Airbnb that was very nice. All in I spent around $600, including meals and accomodation..
For these reasons alone I would suggest you should go only if you limit yourself to 1 day and not stay overnight (it's not exciting enough for 2 days), then it might be worth it. However I had a strange experience that will ensure I never return. The $9 locker requires a $20 key deposit. Since we were staying for 2 days, I kept the locker key overnight. When I came in in the morning, I wanted to ensure that we still had the locker, so I asked and they said I could still use it but that I would not get my deposit back because I didn't return it at the end of the 1st day. I spoke to two seperate employees about this and got the same tune. When I mentioned that given those facts, I had no reason to return their key, they said they know. I suggested that this wasn't very safe for the next person because I would have a key to their locker, but they were not swayed. I am sure I am not the only key holder out there, so beware if you trust your belongings to them. When I told them I was planning on writing about my experience they said that was 'understandable' (that's a quote from the employee who kept my deposit). I've been to the water park in Queensbury, New York and I would recommend that one or Bromley Mountain as an alternative. Good luck!
