We used Boggy Creek Airboats on our last trip. It was close to WDW; I believe it was in Kissimmee. It was fairly crowded. We arrived at 1pm or so and had to wait until the 3:30 boat for our ride. They have a small gift shop, snacks and picnic tables. The ride itself was fun. We only saw about six alligators (including two having a nasty fight!). There is also a swamp buggy tour that you can take, although we didn't try that. The boats are fast and loud, but I thought it would be more of a thrill than it actually was. Plus, the ride seemed to go very quickly after all that time waiting. Still, I'm glad we went but don't know that I'd bother to do it again.
