I'm no "Road Warrior" in a hotel every night, so my experiences with Marriott's measures in the very low double-digits, not the high triples of many of you.
That being said, I choose Marriott for many reasons, and one of them is Customer Service. Be it a Category 6 Marriott in a major city or a Fairfield Inn out in the middle of nowhere, I am always made to feel welcome and any concerns or issues I have are always taken care of quickly and without drama.
