Michele and David also did the same for us. My son (17) did his diving training with PADI in Calgary, and thanks to the Tripadvisor reviews of Isla Tortuga, I got hold of Michele. He arranged to take my son (and me) for his qualifying dives - just the two of us, with Michele.
The most patient instructor, he re-assured himself of my son's training, taught us quite a few handy tips, and took us first for a 7m dive to evaluate us in a safe environment. Not being part of a group made it very easy for my son to relax, and Michele could focus on his training one-on-one. They also arranged taxi transport from the hotel and back, and treated us with tasty traditional Italian and local dishes on the boat.
With David as skipper, Michele, me and my son, spent two days together with four lovely dives, in difficult windy conditions, and we parted as friends. Very highly recommended, and thanks again to the Tripadvisor reviewers - the info on TA is invaluable when planning a trip to a new destination.
