Where to start? Amazing only begins to describe this experience. We have done a dolphin watch experience in the past. We lined up with 20 or 30 other jet skis from multiple companies and they track the dolphins behind a fishing boat. You might get within 20 or 30 yards if your lucky enough to be in the right position. We had Avi and the wildlife all to ourselves. He is a man that loves wildlife and he made sure that we had a great time but never at the expense of the animals. If he ever felt we were stressing them he would move us on. His knowledge is incredible and, although he takes this trip likely multiple times a day, his excitement at every encounter was often greater than ours. The water around the 10 thousand islands is largely smooth and allowed us to open the machines up for an exciting, winding ride at speeds that were never beyond our comfort level (but fast!!). If we ever return to Marco this will be at the very top of our list. I can't deny it is fairly expensive but not out of line with others. Be mindful of the tip on the ipad. I was happy to offer a tip and in my excitement of the adventure we had just had, did not pay close enough attention to recognize that that the numbers are percents and not dollars. An incredible day!
