Just got back from Florida a couple weeks ago. If you get chance to get down to the Keys then have a look at
Aircraft Floats ultra light pontoon floats from Highside Ultralights Key West EP Dalton keywestfloats.com north carolina web design asheville $200 for an hours flight in a floatplane ultralight most of it hands on. Great fun flying 200ft over the Keys seeing sharks/turtles in the water below you.
If you want to see some gators, then I can recomment
Tours in the Glades who are in Florida City. Lets just say we had to poke a gator with a canoe to get him to move out the way!
