You can actually check out the excursions through the Holland America website. They have an e-brochure for each region...this cruise will be in the western Caribbean and all of our ports are listed with the excursions offered.
However, through our experience on the last cruise, not every cruise offers every excursion in the brochure. On our last cruise, one of our ports was Cozumel and we really wanted to book the Dolphin Swim Adventure. Well, the more interactive excursion we wanted to book was not offered on our cruise, only a dolphin encounter so we actually ended up booking the Dolphin Swim Adventure on our own with a bunch of other ladies from the cruise. It was tons of fun and it was much less expensive!
We won't actually be able to book our excursions for this cruise until about 30 days prior so you've got plenty of time to think about what you want to do in the ports.
Hope this helps!
