Probably my 6th trip with Avi and I'm finally getting time to review it. This guy has his heart and soul in this tour, from the history of the area, the wildlife, the dolphins, the manatees, the shelling, the mangroves, this tour has it all. If you do nothing else when you are in Marco Island, take this tour, it will be one of your highlights. We have never been disappointed. I live here and still learn something each and every time I go out on one of Avi's tours. My friends and relatives mention the fun times we've had with Avi and the passion he has for the area and Marco Island. You won't be disappointed. Thanks Avi!
