Off-season tours can be difficult, especially for birding and wildlife viewing. For our family, it was great, because we had a tour all to ourselves. Our tour guide was knowledgable about both natural and cultural history of the area. She was very engaging and enthusiastic, and kept us moving at the right place. She and both the airboat and boat captains were very accommodating, and worked hard to get us good wildlife views. Even in the heat of summer, we managed to view over 40 bird species, plenty of alligators and a combined family of dolphins, along with tons of great photos to remember it all.
I definitely recommend these folks for the great service they provide.
