Walk on sandy beaches. And, mainly, dive. Cozumel must have the largest variety of depths in the world. We snorkeled almost every day and could have spent another week without repeating a reef. For scuba divers the possibilities are even greater.
Nighttime activities are limited.
There was music and dancing on the main plaza Sunday night. Otherwise we ate late, read and slept early. We had breakfast in our villa and ate out for dinner and supper. Mexican and Mayan altho Itailian and American were also available. However, Montezuma got his revenge.
