We currently have a 4-night Disney cruise booked but have been wanting to change to a 7-night but no family oceanview rooms have been open. Finally there is a quarantee open today but DU agent has not emailed me back yet. Can I book it myself and still get it changed over to retain my 10% on board booking discount??? TIA for any help! Update 2/15/13: My Dreams agent came through and got us the room we have been waiting for yesterday on Valentine's Day...best V-day gift! They were great and kept checking every day till they got it. We have used them for our last few cruises and will definitely name them again when we rebook another on board in June! Thanks DU and Tracey!
