We used WAhoo tours in Cozumel. It was a $6 cab ride to boat and it was just for the 4 of us on the boat. Husband, 6 son & 7 yr old daughter. Our guides manny and miguel took us away from the crowds and he actually was in the water with us leading us with a bouye (sp). The part I liked best was that manny would bring the boat to where we ended so we did not have to swim back to the boat. We saw parrot fish that were so beautiful and the water was like looking trhough glass. They also supplied beer, soda and water. We brought our lunch. We were out there for over 3.5 hrs and all of this cost less than $300.00 for the 4 of us. We booked through shore trips but they have their own web site wahootours.com I would highly, highly recommed them and ask for manny and miguel.
