Don, If you go for a week next year, you'll want to got for two weeks the year after. In addition to the C-B-B, there are places such as Joe Overstreet Landing, Fort DeSoto, Merritt Island Wildlife Refuge, Wakodahatchee Wetlands, Viera Wetlands, Orlando Wetlands. While you that far south, you might as well go to the south end of the state and maybe even venture down into the keys. On the way down, you could visit St. Mark's Wildlife Refuge and visit the lighthouse. If you make the trip down a two-day affair, I'll suggest staying at the Wakulla Lodge, south of Tallahassee.
I could spend a year or two visiting the places I want to visit and revisit in Florida, and I'd likely not get them all done. That, and go to Prattville for the mills and river guided tour.
