hi; we hope to catch the ferry from PDC to do a day trip to cozumel - 2 adults, 2 kids. As we won't have transport, I am wondering what we do once there, how to get around etc. We are not interested in shopping; more interested in snorkelling, also just relaxing/beach etc. Is there any local transport to a good place, or do we pre-plan a tour, or what?
many thanks, michelle
