Just noticed that a one night stay last month at a regular Marriott was not credited on my account. What a hassle - I have to get a copy of the hotel bill from the hotel and fax it along with the missing stay request form. Then who knows how long it will take to get it credited. It's only one night so it is almost not worth it but I earned those points, darn it!

How often does this happen to you elites out there?
