My cousin winters at Upriver (at Fort Myers), together with a group of other bikers who ride around from bar to bar and party a lot when they are together in the campground. The CG is pet friendly as well as biker friendly.
I assume your "reasonable" is about cost. South Florida costs what it costs, there is not a lot of variation except that it tends to cost more being farther south or closer to the beach. But whatever the cost, if you like to party with old bikers, Upriver is worth looking into.
