I hope I am not opening up a can of worms here but her goes. There seems to be an unpublished fact about Topsail. There are about 28 sites that "some" people book for 30 days at a time. That is about 17% of the sites. You call Reserve America and they don't know about them. I book two weeks in the spring and two weeks in the fall, I go by the published rules. There are always people on certain sites that are there when I get there and they are still there when I leave two weeks later, they are some of the same people I see year after year. That is one reason it is very difficult to get a site at Topsail. You will be hard pressed to get any information concerning these "longer term sites". I was told this is the only Fl. State park this is done in. I don't know if "they" allow this in the middle of the summer or not, because I am usually there in May and September.
