We got our own taxi and explored on our own. This was our 4th time to Cozumel and decided not to schedule anything. We had a great time there are many taxis right at the port and the cost were minimal.
Excursion to Good Hope with horse and buggy ride. The excursion was nice, and informative however the horse and buggy ride was very very short. The excursion could have been about 1/2 the time and been OK. :)
Dolphin encounter and beach break.
Encounter means you get your picture made with the dolphin and can touch them for a minute or two, nothing like the dolphin encounter in Mexico. That part of this excursion was a waste of time and money. We also had lunch which was a little sandwich, chips, and a can of beer or a few soft drinks, and or water. The beach in Grand Cayman was beautiful and wonderful break in December but the excursion was not worth the money paid. We should have done just the beach break.
