I went on this same cruise last June, and Diana Ball has given you some great information.

I would like to add that a shore excursion not to be missed (especially if you like Mayan ruins) is the tour from Costa Maya to the Chaco-Ben ruins near Belize. This doesn't get as much attention from cruisers on Princess, but it's an opportunity to see ruins (including pyramid, that have been uncovered in recent years and are still being uncovered. Only Princess passengers are allowed right now to go to these ruins. You are right in the middle of the jungle, and it is so quiet with occasional sounds from the monkeys and birds. You can walk right up to the pyramids, sit on them, and climb the pyramid. This won't be allowed in the future. It is very quiet and peaceful there like in the ancient days.
