I received this back:
Dear Xxxxxx Xxxxxxxxx:
The "Silver Elite Double Points" promotion is a promotion sent out by our Corporate offices. I apologize that our office has been advised that no Platinum or Gold members are eligible for this promotion. Corporate is trying to get our least frequent stayers to make more stays with this promotion.
We will have future promotions that benefit you, our most loyal members, for example: The "MegaBonus" promotion, where you earned 20,000 points after qualifying, when most Silver members only earned 10,000 points.
We appreciate your continued loyalty to Marriott and look forward to serving you again soon.
Sincerely,
Xxxxx Xxxx
Marriott Rewards
