Since cruise ships are only on shore for a couple hours, we were recommended a tour guide - he cost a fortune! We ended up turning him down because he didn't even speak English that well. Then we were walking and saw some friends that we met on a cruise talking to this guy on the corner of the main road, in front of that divers statue... anyway, we chatted and turns out he was a tour guide that had cars and a whole package. He called his boss and asked if 4 more people could come on the tour. She said yes. We paid, got our own car. It was so simple... we went around the whole island, snorkled, went to the first Cozumel settlement: el Cedral. I learned so much on that tour and I could understand everything he said. Omar was great! Their e-mail is firstname.lastname@example.org and I will recommend them to anyone that goes to Cozumel!
