Oh, ok! I think I see what is going on now, and it is a good learning experience.
1) A reservation was booked while onboard an earlier cruise to save the 10% discount and $200 room credit. The date chosen at this time was arbitrary (like sometime in October for instance).
2) This ressie was trasnfered to
Dreams Unlimited (or another TA) for them to hold and with standing orders to transfer it to a repositioning (or other summer cruise) once they are available.
3) During the mad scramble on Wednesday, DU (and other agencies, including
DCL) were flooded with reservation requests. It has been stated in other posts that DU was swamped and only completed the last resservation in the wee hours of Thursday morning. To handle the load, the TAs simply made a new reservation instead of transfering the old one, thus the party has 2 ressies.
4) Once a second seperate reservation is made, it is difficult (or impossible) to transfer the 10% and $200 incentives from one to the other. The whole initial ressie needed to be transfered, instead in order to get the discounts.
5) Transfering the original reservation now would cost lots of extra money, since to do so would be at the sailing's current rate instead of the initial rate at release. You can still canel the 2nd reservation and transfer the 1st, but your seating and pricing would be lost. The 10% discount would now be applied, but it probably would not outweigh the base price of the 2nd reservation, propting you to cancel the 1st ressie instead (and loosing the $200 room credit).
6) I guess the lesson to be learned for the rest of us would be this. If I book an onboard resservation intending to switch it to another sailing not yet announced, it is best to keep that ressie with DCL until the new sailing comes. Then I would contact DCL myself to have the whole thing transfered to my prefered sailing date. Afterwards, I would then transfer that whole package to a TA (like DU or Costco) for the additional rebates.
Let me know if this isn't right, since it is a wonderful learning tool for most of us on how the Reservation process works (this whole event has been an interesting study).
I wish all of you on the dark side of this the best of all luck, and I am sure they will be able to straighten it out, especially when the unused cabins go back into inventory. Please do not give up hope!!
