It was very interesting. Our tour guide had studied the Mayan culture at the university level and was extremely knowledgable. The ferry ride from Playa de Carmen to Cozumel was great to. Six of the college rowdies got sent home from here when we docked. They were so obnoxious that Carnival flew them home and refunded the balance of their trip.
Deck chairs are scarce as are towels.
Lots of fun activities. Two more rowdies sent for starting a food fight at dinner last night. The cruise director said to take bread with you to feed the fish. So I took some from the dining room at breakfast. When were about to get in the water after our instruction, neither of us had snorkeled before, I put the bread in my swimsuit pocket and got in the water.
