After I called the PP line today, I found out a new tidbit of information about posting of points and nights. If you book through a conference (and you must pay for it yourself, which I did), the postings will not happen until usually ten days after the stay or whenever the conference forwards its info to Marriott. Fortunately, the Customer Service Representative called the Chicago Marriott and located my file and manually posted the nights and the points.
But what difference should it make in terms of posting that you've booked through a conference if you've paid yourself, checked in with your Rewards card and checked out at the end? The rewards number is on the bill.
PS - After I tried to post this and was asked for location I got the following error message:
And the key point to me is I don't know if I ever would have gotten the credit had I not called. This has happened so many times to me that it is ridiculous, though mostly after European stays. Last Marriott USA stay was January at the Boston Copley Place, and while I had serious issues with the lack of CL, they posted my points right away even though it was the same conference stay. So beware those of you who pay through conferences -- monitor your account!
