I don't know much about investments or the housing market in Florida, but I know I like Celebration. Stephen and I took a tour of the properties last September. The houses are gorgeous. There are a number of options from apartments to huge houses. I have heard one person complain because of all the tourist who drive through there looking at the properties. If you're wanting privacy, that's probably not you're option.
Good luck and I hope someone else can talk about the investment side of it.
