We are going to be in Cozumel in Feb. next year, and want to rent a Jeep and go out on our own. We did this in 07, but rented from Enterprise and were less than pleased. We had a great time on our own and had no problems driving in Cozumel. We were able to go the the other side of the island. It is less hurried, and very pretty. If you know anything about Ernesto's please let me know. Good, or Bad.
