IIRC, Blockbuster was fined in U.S. for a concerted effort to add bogus late fees to accounts knowing most people more likely to shrug and pay the few dollars than fight it. A few follars here, a few there and it adds up. And while not wanting to paint all Marriotts with the same brush, I can't help but wonder having gone through similiar things as the previous posters whether the individual hotels have opted for the same tactics. Maybe that's the skeptic in me, but it's just a thought I've harboured for a while...
