I called MR on Tuesday and they agreed that I am owed the 90,000 points. I elected to forgo enforcement of the $100 cash + 1st night cost portion of the guarantee, but I am beginning to regret that.
MR spoke directly with the FD manager Tuesday, who agreed to post the points within 24 hours. I called back Friday as the points hadn't posted. MR called the hotel and the manager was not in -- they left a message. I was told they also opened a case with some department (I can't remember which) at corporate, who would resolve it within a week if the hotel does not cooperate.
I suppose the extra calls are worth the 90k windfall, though.
