This past July 24th cruise we were offered an upgrade to cat 3 for $1200, and were told it was very rare to have a suite available.
We had a cat 5 and 11 across the hall booked . We told them we would like to do the upgrade, but then when they went into the computer they had to apolagize because it had just been taken by someone else.
Oh well. We were just happy to be cruiseing because we had lost our birth certificates and were very afraid they would not let us on board. All went well, and we had the best cruise of our lifetime.(and this was our 6th cruise.)
