Moorings, of course, are a lot cheaper than a slip, but then you need a place to keep the dinghy when you are away from the boat. Some places charge just for a dinghy tie-up. Have you thought about checking the classifieds for Cape Coral? A lot of people on canal-front homes don't use their docks, and gladly rent the docks out to boat owners at a reasonable price. You'd be a lot closer to the Gulf, to, than if you were to come down the river from Ft. Myers. There are places to anchor behind Ft. Myers Beach, if you wanted to check into that.
