My family did this year before last. We really had wanted to see a little bit of ruins, and that is what it was. Our main problem was that it was in JULY and so hot. The ruins were great, and we saw some cool wildlife, but it was crawling with bugs and so hot people were pouring water bottles on themselves. The ride to the beach was bumpy, but we laughed about that. The beach was great, because we couldn't wait to hit the water. The beach time was too short! Last summer we returned to Cozumel and planned an all day beach trip just because we were returning in the summer and wanted to be able to cool off. You must be going at a much more comfortable month, right?
