Ditto the comments about Fun n Sun. Very small lots except for the few that they have combined two to make one for those with money to burn. Park is really showing its age. Friday night dance attendance is about one third that of ten years ago.
Alamo Rec-Veh in Alamo, Texas is a low cost option. Quite a few Single folks, who get a single's discount. Remote control boats (on private lake), remote control everything else. RC car race tracks. Indoor pool. Woodworking shop. Shuffleboard. Music jams. Etc.
In other words, lots of parks have lots of activities and the rates are all over the place.
