We had this happen to us last year. We had a cat 7 reserved for 334 points, and it dropped to 290 points with a $150 statroom credit. Also, since the special last year had the same point requirements for cats 5-7, we were able to switch to a cat 5 for the same 290 points (This was for the 7 Day cruise).
JonHM,
Last year after we got the call, the special was listed on members website under Member News. It doesn't look like there is anything there yet, but I would expect to see it there in a few days.
