Change C+P into point stay
I have a 5 night stay coming up at the Meridien Phuket. I booked it on C+P but would like to change it to a full points stay (pay 4 for 5 nights). The website shows no point stay availability, due to room type not available. However I already have the appropriate room in my C+P. My ambassador tried and was told it is impossible.
I thought I would check here for ideas.
