Sounds similar to Santa’s Village in New Hampshire. Somewhat close to Story Land in the White Mountains area, but I can’t remember the town it’s in. Jefferson, maybe? It was alright when I went as a kid, but damn hot. I think they’ve since added a water park so that’s an improvement, but it definitely needed more shady areas at the very least. I want to Indiana last year and do find it to be nice state, so I’ll have to consider Holiday Park if I ever go to Santa Claus.
