I've visited twice now when a church group was having an event in the park. Our group rents out a group cabin area, complete with its own bathhouse & kitchen-lodge.

The cabins themselves are rustic - one-room, with bunkbeds or cot-like beds, depending on your cabin. They've obviously been being used for years for school and scout groups, as they are covered in kids graffiti (mostly just names & dates). I like the rustic cabin idea, but the screens in the cabin windows have badly needed repairs on both of my trips, so aside from mosquitos you end up contending with wasps too. The bathhouse is not well taken care of, & the bathroom attached to the lodge/kitchen is disgusting. I suppose for the church's purposes, the price is good & the area works. For a big group it's nice to have the whole area to ourselves.
