Most of the other cruise lines are making similar offers. To everyone planning to cruise this weekend from Florida, be sure to check with your TA and/or your cruise line - go to their websites, as their phone lines will likely be very tied up, and several of them are posting regular updates on their websites. In general, cruises leaving Thurs. and Fri. have been cancelled, and those scheduled to leave Sat. (and perhaps Sun.) are postponed for a day or two; virtually all are offering some compensation - at times quite generous - to their passengers.
Have a great cruise, Tom! Good luck with the hurricane, both getting to the cruise, and at home!
