If you have the opportunity, also go down to Sebring and see Highlands Hammock State Park - http://www.floridastateparks.org/hig...ck/default.cfm. It's less than 2 hours south of Orlando and was definitely a highlight of my trip to FL in June, even though it was so dry that the swamp trail was dry.
edit - back to the topic . . . those are cool photos and I'm glad I've never seen photos of what was probably nearby when I was swimming in FL as a kid. I used to love swimming among the fish. Like a lot of things that were cool then, it seems so stupid now. I'm not sure which perspective is better, but the current one seems safer.
