I can't even book SPg properties using points. My accounts are now merged under my new Marriott number. When I go to book a SPG property using points, it says I have enough points, but when it goes to my name, address, etc, it says my SPG number is wrong and I should change it. The number can't be changed and is my new Marriott number. I'll wait a couple of days and see if this works itself out and then I'll start calling.
