Heres a few to call/try: Jetty Park, Port Canaveral (on ocean and can fish and watch cruise lines come in),
Rock Crusher Canyon (west coast) big wooded park with huge heated pool, x2 Anatasia in St Augustine,
Sebastian Inlet park (right on the inlet! Lots of fishin'), Long Point Campground on A1A south of Melbourne Beach near Sebastian (rural setting). x2 for Topsail...worth a few nights at least....BUT check the weather, it gets cold in the panhandle, we're going to Fort Wilderness at DisneyWorld for the first time in Nov...can't wait for that. Many great reviews on Disney campground.
Check rvparkreviews.com and that should give you ideas of areas you would consider staying.
There are many, many campgrounds down here, come on down..the waters (sometimes) warm.
Safe travels
Andi
