We love Fort Myers and Fort Myers Beach. We like to be close to the beach and Sanibel. Gulf Waters is a very nice RV Park and you might want to check with them for availability. I just purchased an RV lot in Holiday Condo, Inc in Fort Myers. I think there are a few available rentals there. It is not a high end RV resort but it meets our needs. The problem is the office does not get involved with rentals so you have to find an owner and deal direct. Holiday Condo is about 3 miles from the Sanibel Causeway and very close to Fort Myers Beach. The park is mostly park models with RV lots scattered through the various streets. The lot sizes are about 34 feet by 65 feet. There is a heated outdoor pool, an indoor pool and the usual activities. I would guess most owners rent the lots for between $700 to $1000. Go to google maps and see if you can get a feel for the looks of the park. If you want I can try and find a phone number for you to call a lot owner that has availability.
