Mister Internet,
I basically agree with you, except for one minor quibble:
I am a long-time Platinum Marquis member of Marriott Rewards, and I don't get extraordinarily good treatment. I am treated courteously and generally -- but not always -- get the upgrades, etc., to which I am entitled by virtue of my status, but no bowing and scraping, that's for sure! What do they do for you?
Bruce
