Welcome from Happy Valley, PA. We lived just north of you in Orwigsburg for 5 years. Loved that part of the state... Land of great family owned restaurants.
There's a few threads on here that talk about the three main campgrounds for Knoebels... Knoebels on-site, J&D's (just down the road) and Lake Glory (Knoebels owned and fairly new but a few miles away).
If you're looking at Hershey Park, there are a few of us on here with suggestion as well.
Good luck with your new unit.
