Are there any sidetrip tours for a day to Cozumel? And if so, what do they usually include? If I remember correctly, and I wouldn't bet my life on that anymore, my daughter and I did such a day trip about 20 years ago. It was a full day tour: boat to Cozumel, a black coral factory tour, a lunch on a private beach, snorkeling if you so chose and time for shopping at the pier area before the ride back. I don't see anything similar to that advertised anymore and was wondering if something similar still existed.
