We all went on the Tulum excursion in Cozumel which was not pleasant. The ferry ride made many people sick, the tour guide/salesperson on the bus was very interested in persuading us to make certain purchases from specific retailers , and we took a mandatory 20 minute stop at a gift shop five minutes before getting to Tulum. Once there, the ruins were cool but the best part (which redeemed the trip) was the beach. It was the most beautiful beach I've ever seen. We swam until time for the bus to leave.
