I've never been on an airboat tour around here, mainly because I much prefer driving the airboat rather than having someone else drive. This is only due to experiences when I was younger. That said it depends on what you are looking for in a tour, are you looking to see alligators, old Florida swamps and sawgrass, or just want the experience. I know there is a place down 50 that looked pretty nice near the Lone Cabbage, also in Oviedo there is a place called Black Hammock that does tours out on Lake Jessup.
