We are back from our cruise and had a great time in Cozumel. The dive op WAS Sandollar Sports and they did a great job. The crew was very nice and did everything for us. Changed over our equipment to the next tank, helped us get into our BC's, etc, etc. Definitely earned their tips. The divemaster was very good also and very safety-oriented. I felt comfortable diving with him. Our first dive was to 80 feet on the Santa Rosa wall, which appeared to drop off into the abyss as far as the eye could see (which was a good 120 feet or so!) and had a lot of nice swim throughs. Our second dive was to 45 feet on Paradise Reef which was a patchy reef with some nice coral formations where many HUGE lobster and crabs lived. We also saw an octopus, spotted eels, a sea turtle and a cuttlefish. Very cool. We had good weather as well. Calm seas with 82 degree water. All in all a good experience. I would definitely dive with Sand Dollar again.
