I am trying to remember some of the books that we first used. I think if you looked for "undiscovered" or "natural" and Florida on an Amazon search you would find many "uncommon" tourist books.

I would agree with the 'Brit's Guide' or the 'Unnoficial Guide' for a first time visitor or for those interested in the theme parks, but for those that are looking for a wee bit more just start to pick an choose from many other guides.
