Adult Campgrounds

I would google search '55 and over' park resorts for the area you desire. You should hit a few. While not restricted, they are not 'kiddie' parks and alot of times have very few in the younger age group. So you weeded out alot of people. Also they sometimes have 'adult pool' only etc. Amenities restricted for the adults which gives you a younger free place to have fun.

I also am shocked at the poor responses on the thread. Geez people. Slow day for ya'll. Had to find something to attack as usual. OP asked a simple question.
