=welcome aboard... congrats on your first cruise! My first was on the Sun Princess, sister ship to the dawn and it was wonderful. You have picked out a fantastic first itinerary, you will be very pleased. Ive never been to Tortola but it is also said to be quite beautiful, I am jealous! Check the Princess website at least for ideas of whats offered in these ports, then come back here and do some searches in the community and caribbean boards for each island specifically. There is TONS of info here. Ship tours are great for first time cruisers because they look after you and it takes the planning and worry off of you since you are unfamiliar with all this stuff. But if you feel adventurous, then look into booking some tours independently. Again, lots of suggestions and help here. You can ask specific questions and you will get some advice. For example, post a thread called "first time to Barbados, need suggestions".. etc, things like that. The people here are really nice, and most are willing to help. Have a great time!
