I too have started booking cruises (other than the weekend ones) to ports of call I have not been to or perhaps to one I want to return to.
Nassau does not call to me at all. I think of it as the armpit of the Carribean and may only go to the beach via the bus.
My next longer cruise will be a repositioning, that starts in Colon and goes to FLL; it has the advantage of a bonus day in Aruba (one of my favorite places) and 3 days at sea.
Looking forward to your review of the Pearl.
