I've got one of the corner 9A rooms booked on the Fantasy. It appears to be a different shaped room than the other 9A's. (Rm. 7504) However, I am about to move up to a cat. 8C instead- knowing it will have seating and a larger porthole. After searching, I've read several different things about rebooking. I want to make sure I understand clearly. When I am on the Dream in April and I re-shop my Fantasy cruise- Will I be able to keep my same stateroom? I've read where someone stated that there has to be availability in that category. If the room is already mine, why can't it just stay mine even though there could possibly not be any other rooms left in that category? Is this something to worry about? Thanks!
