I have experienced the same problem too. My cabin dropped down for about $600. I already paid in full. We called our travel agent and they said they were not able to adjusted our price. However, they did updraded us to the next category (AG to AF). I don't really need the updrade because the room is the same and it is only a few room down the hallway on the same floor. But I do appreciate his willingness to help.So, if your cabin price dropped, do call them, may be you will get something back.
