Thinking about doing a camping trip/dive trip this summer(June-July) to the Florida Keys but I am wanting to be able to move around every couple days to different locations, moving down through the different Keys as I drive south. Would it be possible to do this and not have to book the camp site in advance? I would like to have the freedom to stay in a spot till I felt ready to move and then go to the next camp ground and get a tent camping location for a night or two and continue that pattern. Can it be done?
