when i was a kid my best friend's parents had a trailer in a camp ground. it was cool cause we were "locked in" on the campground and couldnt get off grounds without a parent. We could go to the pool, bay, clubhouse for billiards, parties (they would have christmas in july, halloween parties where we wore costumes and went trick or treating thru the camp ground).
It was someplace safe for parents to take kids. and it was not very far. No different from people having a shore house, or ski cabin. We jet skiied, water skiied, and fished and had a great time. made lots of friends. The parents just relaxed while the kids did their thing.
