If your stay is going to go to a master, get your Marriott res. # and while not logged in, put in that number and edit the stay, adding your Bonvoy # and your email. It will then appear in your account. Still not a guarantee you'll get the points/credit, but I'm better than 50% using this method.
On the very rare occasion, this will trigger your CC you put down for incidentals being charged the full amount. I can usually get this corrected, but honestly hope they don't because them I'm definitely getting full credit.
