We cruised this itinerary/ship last March. It was a busy week, with only one day at sea. If conditions are right, and your captain feels adventurous, you will sail past an active vocano on Monserrat sp?. Pretty neat! Beautiful ship and ports of call. Have a great time.
I am going on the same cruise but on 3/19-3/26 so I will be happy to share the experience upon my return. I am booked on a few excursions outside of the cruise lines doing some snorkeling and sightseeing. Catch you later!
