Hi Gouodux, welcome to the DIS.
I am going on the 5/28 Mexico cruise. If you go up to the top of the page, you'll see "CRUISE MEETS". If you click on that, you might find some other people that are on your same cruise.
This will be my first
DCL cruise so I don't really have any tips. All of the ports, except Puerto Vallarta, are new to me. And when I went to Puerto Vallarta, I got sick as a dog so it's basically new to me too.
