You never really know for sure. I have a cruise booked and I looked on the Cruise Personalizer and they upgraded me from a AD to an AA. I went back and the cabin # and cat had changed to just AC guarantee. I am due to sail next month and looked again and it has a cabin # and Cat AB. I am not sure if it will change again. Some posts say that they even upgrade again at the pier (very rarely...but does happen once in a blue moon). I am very happy now with the cabin I have. I paid for an AD and got a AB, and my TA took $$ off when the price reduced and gave us 15O.OO onboard credit to boot. Have a wonderful cruise.
