When I first went down for halloween 6 or 7 years ago, they upgraded me mid stay. So I had to move sites half way through the trip. I probably could have said no, but they gave me a full hook up instead of a tent site. Originally planed on taking the pop up but bought a TT before arriving. When arriving they checked and asked if I wanted a full hook up for half the stay as we were thier for about 11 or so days. So wait a real upgrade, but they try to accommodate you.
