So far it looks like there are no changes to the Sept 7 sailing (today) of the Disney Wonder (the Magic is undergoing updates so is not sailing) due to Hurricane Ike and given Hurricane Ike’s projected path, it looks as if the Wonder will not be impacted by Ike.
It also appears that most cruises with a Bahamian itinerary that leave in the next 24-48 hours should be in good shape since Ike will be clearing out.
Ships visiting Key West between Monday and Wednesday could be impacted as could ships that are sailing in the Gulf of Mexico.
