If you are even thinking about doing this tour then you need to book it. We ended up with Captain Chris Passmore and to say that he was awesome is an understatement. Chris clearly knows where to find the wildlife including the primary reason everyone came... gators (we saw 5 large, and several babies). But on top of that there was a bald eagles nest (with the mom), turtles and various species of birds.
Chris is also a pretty funny dude while still be knowledgable about his job, he clearly enjoys what he does which make the trip that much more enjoyable.
As for the airboat, high quality/safe and exactly what you would expect when you picture going on an airboat tour.
