I'm not sure if this affected us becasue we secured our cabin late, but I was glad I confirmed my reservation in the
Disney Cruise line system. I entered my reservation number in the
DCL systems and they showed us booked for a 3day Carribean Cruise leaving 9/1.
I called DVC yesterday and they confirmed there was an issue. They called me back today and said it happens every year and they hold back some cabins as a result. Long story short, we are still on the cruise, but in a different cabin on the same deck.
So I would suggest confirming your reservation.
