Well, looks like I was correct about the Legend... I'll compile all the changes I have and post them in another thread...

CARNIVAL LEGEND – 8/19/12 DEPARTURE
The Port of Tampa is expected to close by 3:00 AM on Sunday. At this time, they are uncertain as to when the port will reopen. Therefore, we have made arrangements to dock at Port Canaveral instead, where we will arrive at 8:00 AM on Sunday. Busses will be available to take guests to the Port of Tampa or the Tampa airport. The parking garage at the port will be open. It will take approximately two and a half hours to the Port of Tampa from Port Canaveral.
CARNIVAL LEGEND – 8/26/12 DEPARTURE
Due to the expected port closure in Tampa, the Carnival Legend will dock in Port Canaveral on Sunday. We ask that guests proceed to the Port of Tampa and plan to arrive between 10:00 AM and 3:00 PM. The parking garage at the port will be open to park your vehicle. We will have busses available to take you and your luggage to Port Canaveral. Please do not proceed to Port Canaveral directly as the ship will be docking in Tampa when we return next week.
It will take approximately two and a half hours to Port Canaveral from the Port of Tampa and no adverse weather is expected. The last bus will depart from Tampa at 4:00 PM and we expect to sail at 8:00 PM.
At this time, our itinerary remains unchanged. However, there is a possibility we may have to make changes, depending on the path of the storm.

Thanks for the updates Charles.

Isaac has been no big deal in central Florida so far. It has been cloudy with a few sprinkles today. It is odd to see the clouds moving east to west. It's usually the opposite direction. It just started sprinkling again a few minutes ago. We're supposed to get rain & wind overnight and in to tomorrow.

Thanks again Charles!
