Just be sure to drive carefully. The is quite a bit of traffic right in town, but once out of town, there are many wonderful beaches to visit. Check out the various beach areas of Cozumel at
www.CaribbeanPortReviews.com. You will love Chen Rio if you are looking for a vacant paradise.
All of the ports you are visiting are safe and friendly, but always be aware no matter where you are.
Hae a great cruise!
