We didn't see much of Cozumel because we went to the mainland to see the Tulum ruins. If you get seasick easily I wouldn't recommend the ferry to the mainland. The ride can get pretty rough. I am a commercial fisherman so it didn't bother me at all, but my wife and I were looking around and some of our fellow passengers and quite a few looked a little green.
It takes more time to get to Tulum than you what time you have to spend there. The ruins are worth seeing, but for me were not really the highlight of the trip. I had never been to Mexico before, and on the way back form the ruins to the tour bus there is a restaurant called Frosty's that is recommended by the tour operator, who warned us that some of the other restaurants nearby overcharged and took advantage of people. I had some tacos and a very good margarita. This is also a very good place to get some bottled water. It was 37C in the shade. My wife unfortunately didn't eat anything. She was nervous to be in Mexico because she pays too much attention to the news, but her fears were unfounded.
I would highly recommend booking this excursion with the cruise line because of the tight timeline. If the tour is delayed at least the ship will wait for you.
