To follow up on the saga of the denied SS certificate:
After e mail correspondance with Marriott Customer Care, I was offered a $50 Marriott certificate to compensate me for "the confusion" about my rate.
While I appreciate the gesture, (and it does recover half the value of the errant SS certificate), I think only the Marriott folks are "confused". I have printed confirmation of the rate I reserved at and what it covered, and made a phone call to the Platimum Line to specifically ask whether I could combine the EOO with that rate. The answer was affirmative. I honored my end of the contract I entered into when I reserved the room, and Marriott ought to honor their end. If there was any "confusion" it was on the part of the Platinum service rep who apparently gave me bad information. I don't feel a good Marriott customer should literally or figuratively pay the price for their "mistake", if in fact it was a mistake.
Would the Marriott guru on the site care to comment?
