Cute pic! I am really jealous that you are getting ready to go. My next big vacation is SO FAR AWAY! And I am finding out that planning a cruise is not nearly as fun as planning WDW... there's only so much you can plan...
If Nassua is one of the stops, I would suggest looking into going to Atlantis. They have a sister resort across the street, and I saw prices as low as $150/night during my cruise. the resort gives you full access to everything at Atlantis (I wish we had done this as we spent about 1 1/2 hours on Nassua- unless you want to buy jewelry or cheap stuff at the straw market, there is not much there)
