My problem with this whole thing is that the property would rather hold open a Concierge level room for walk-ins for the remote chance they can pull in an extra $10-$20. Just shows how much your Platinum Elite status is appreciated by those properties.
What's truly short-sighted about those properties is that these people fail to understand that it's the MR program that brings many of us to that property in the first place. As hotels go, a FS Hilton isn't going to be terribly different as a property than a FS Marriott.
