I know that MS cannot book inventory available for cash rooms for someone staying on points. Does anyone have a sense as to whether we could get upgraded at check-in if they still had cash pay rooms available? Using additional points, of course. Or do they as a rule never use inventory available for cash pay in that way? We've been on a 3 night wait list for a 1BR at Kidani for a couple of months, and we just ticked into our thirty period -- so I'm not overly optimistic at this point (can't believe wait list didn't come through for three nights in the third week of September). We have a studio booked, so no big deal, but would really like the 1BR.
