Please help... I am confused about this whole rebooking thing. I am going on the 4th of March sailing and I want to book the 7 day on Sept 11th. DU seems to have the best deal, so do I need to book with DU, then rebook onboard to get the 10% and $200 credit? Or do I just get a quote from DU and give it to Donna and have her book it. My goal is to get the rebate from DU and the 10% and $200 credit from DCL.
