Compared to other hotels and airlines Marriott points seem to often take FOREVER to post. I was just on a trip to DC, and my Delta miles posted for the first leg of the flight by the time I landed on the second leg. It's now been a week and my hotel still hasn't posted.
I know they say to wait 10 days before contacting them, but it just seems odd that in today's day and age it can take this long!
You can get your points and stays posted right away by calling Marriott Rewards. Just tell them you want them posted immediately and the agent will call the hotel, verify your stay and add the points immediately. Some might claim that they can't do it because the stay will post twice but that is not true.
