No wonder this board is so quiet. Some are cruising, while others are at the beach....
I made a similar cruise a few years ago Denisonod. In Gran Cayman was not much to do. I saw hell and bought some vanilla rum in one of those local factories. Best trip in and around Cozumel is the Majan city of Tulum.  I also went to Jamaica, Ojos Rios, beautifull. Cartagena is your last stop ?

For those who are not cruising or relaxing at the beach, a Merry Chirstmas a see you all next year !
