On Sept 12th, the Department of State Issued a Travel Warning concerning US Citizens and the Bahamas, with respect to Hurricane Isabel. It is still in effect on Monday evening, 9/15.
I would think this is a major factor for
DCL when trying to decide the itinerary for the current cruise on the Wonder. If I were steering the ship (like that could ever happen!) I think I would head to Key West, and then back to Castaway Cay again, if possible. If I couldn't get to Cataway Cay again, then a relaxing day at sea ending with a slow trip back to Port Canaveral would be my next choice.
I'm not for sure if Castaway Cay is considered part of the Bahamas, but I think it is. I'm taking into account that even on a 7 day cruise on the Magic, I think you have to fill in the form for travel to the Bahamas. If I'm wrong, someone can correct me.

And the latest advisory from the National Hurricane Center says the position of Isabel is about 470 miles east of Nassau at approximately 4pm est, and it's moving NW at 8 mph.
