I've heard that the Golden is going into Nassau instead of Princess Cays and that Grand is going to Jamaica until they can repare the damage. I would assume that you will get a different port or a "sea" day instead of Princess Cays, unless you are able to go there. We go on Golden at the end of December, so I sure hope we get our private island day, its one of my favorite stops.
My "cruise personalizer" on the Princess web site already shows the change to Nassau Bahamas from Princess Cays for our 11/17 sailing on the Golden. So I've been looking up what we can do in Nassau....looks like either Paradise Island or Cable Beach.
