I'm sorry you are not having a good experience with DU. Waiting 48 hours for a response is unacceptable. So far, my agent, has been very quick with answering my emails. I have discussed with her our plans of reshopping our Fantasy cruise onboard and what needs to be done in order for it to be a seamless transition. According to her, it should be no problem. If I was you, I would contact John with DU and discuss the issues you are having. Good luck.
