Posting my experience with timing and such...I booked a meeting room at the AC Marriott Westport (Kansas City). I stay there alot so its easy to just ask the staff to let me pay for the room for a bit. I used it on June 28th, got my points on the 11th (I reached out to the sales manager to have him look into it, and he manually posted the points), and got my night credits today (the 13th). The sales manager said he didn't have access to manually posting night credits, but they posted on the day I planned on calling into customer service to see what the issue was. Also -- my night/points for the hotel room itself was delayed (may or may not be related) until the 10th. I had to call and ask for my folio to submit an expense report. That is VERY atypical for any marriott i've stayed at, let alone this one...
All told that's basically 2 weeks for everything.
