First let me say, that I've read the boards long enough to be wary of this, and if I had thought about it while working with MS, I would have done this differently, especially since I had enough points that I could have first made the new reservation before making the change on the old reservation.
Long story, short. We had one night reserved at OKW in a studio and then 8 days at ALK in a 2bd SV. The original family that was going to be our guests, couldn't make it, but another couple could join us halfway through our stay, with possibly someone else staying with us up until then. So in order to accomidate this and save a few points, we needed to make a few changes. We wanted to keep the last five days at AKL, and change the first three plus the studio at OKW. Our first choice wasn't available, however, the MS rep. confirmed that there was availability for a 2br at OKW for those dates, which was our second choice. He starts the process, by dropping the first three days at AKL and the studio at OKW, and then he starts to actually reserve the 2br at OKW and suddenly askes me to hold! Right then I knew what had happened and I started to worry. The last night of the OKW 2br wasn't available!!! Fortunately, he was able to get back that night from the dropped nights at AKL, so we are now staying 3 nights at OKW and six nights at AKL.
Lesson learned. Do one of two things. Have MS put a hold on the room when they say there is availability before cancelling current reservation, or if there are enough points available, make reservation before cancelling current reservation.
Has anyone else ran into this same type of situation?
