We were upgraded from tower to tower club two years ago, because after waiting to check in time, there was a problem with the room ( I don't know exactly what because we didn't even get to go up ), and we were upgraded to tower club. When the CM told me the room was on the 12th floor , I asked , the room is on the 12th floor? she said yes, have a wonderful birthday ( it was my birthday actually ). It was actually part of the land/sea cruise , of course they spoiled us with that!
Later on I found out they were sold out for the month basically and since my original room was not available , they bumped us up to tower club. No complaints from me!
