Dave, I never heard of anything like that either. I was on second seating for my transA cruise and I wanted it changed. They said they would put me on the top of the waiting list. I checked my on line docs yesterday and saw they already changed me to the main seating. Now I changed my mind and what the second seating. I'll go to the dining room on embarkation day and try to change it. You probably know that this is the only option you have to change your seating. I wouldn't give up if I were you.
