we were at the CR in January 01 and booked 2 connecting garden wing rooms. When we arrived to check in, we were told that we were being upgraded to a 2 bdrm suite on Concierge.
Talk about luxury. We still paid the same rate as if we were in the 2 garden wing rooms, but had all the amenities of concierge, plus the benefits of the suite. It was the most amazing thing to ever happen to me. Our next 2 subsequent trips, I booked tower rooms and, while another upgrade didn't come our way, we still had an amazing time.
I can tell you that I never asked for the upgrade...it was just given to us.
