My wife and I have stayed a number of times at
Royal Coachman in Nokomis Fl., just a little south of Sarasota. This time of year they're normally full, but can usually fit you into their overflow area. There is water and electric, but longer hoses and electric lines might be needed, but no sewerage. They do have a dump station.
It's a very nice campground, not too far from the beach. It has a very nice heated pool also.
