All I can say is, wecome to Boston. It's leaf peeping season. You may be Premier, but some blue hair from Boca was willing to pay more at the last minute and got the better room. Like all us good soldiers, you made your res early and got a good rate (right?) which doomed you to the standard room. Last week I had to hop around hotels due to lack of availability, not that I'm complaining (Ritz-Carlson one night and Cambridge Marriott one night).
But still, come on, they can't read the reservation? Loyalty at your level has to mean something, doesn't it? A jerk would have made a scene. I commend you for your response.
