Ummm that's interesting. I tried for almost a week to move my expired promo vacation up just one day. I found really great airfare for a Friday-to-Friday stay instead of the Saturday-to-Saturday trip I had planned. Nothing was available except rack room rate. I tried every trick in the book. I tried to add a day at the beginning (no rooms available), I tried to shift the entire vacation (no rooms available). I hung up and tried to get a more "cooperative" CM, and to no avail - (no rooms available). I called so many times over a course of a week; one of the CM asked me if I just called. It was crazy, but it worked itself out. I waited it out and found an affordable rate.
