Have not heard that Cozumel was destroyed due to Wilma. Yes, they were hit with the heavy winds & rain, but, again, not severe enough to close the port at this time.
I have not heard any update on Jamaica either. I know the other cruises have gone there.
Princess & other cruise lines keep passenger safety first at all times. IF they deem the seas too rough or a port unsafe they will alter your itineary. As done this cruise they did a more Eastern route & went to St. Thomas & St. Maarten.
Hopefully by the time you leave things will settle down some.
I do have friends working on the Star. If I hear anything from them I will update you.
Enjoy your cruise
The Star is a lovely ship.
