I've been getting the MAJOR run around trying to use one of these at the Waldorf Astoria New York. The cert clearly states that it's valid at any "standard room" at any hotel within the Worldwide portfolio of brands (and lists out Conrad, Waldorf, etc.).

Well, the Waldorf doesn't offer a "Standard Room"... so the lowest room is a Deluxe Room (at $600 a night). I've called the hotel and spoken to 4 different people, all of whom say that night would not qualify so I don't want to risk it by just booking a room and a prayer. They couldn't find me a single room that WOULD qualify over the next 2 months... I know they are probably busy, but that seemed a little odd to me.
