We are scheduled to arrive in October with Carnival. After checking their tours and prices, we found the Ultimate Cozumel Jeep Tour with Cozumel-Watersports.com. It seems to go all around the island and snorkel at famous Punta Sur park. We contacted them by phone on their 1800 number and they gave very good information about the tour. Their mini-jeep tour goes to the same place...anybody been to Punta Sur?
