I asked the match using my Hyatt Diamond and Starwood Platinum status, but they did not do it. Instead, they said they would give me Gold if I stay 12 nights in the first two months.
It was the beginning of this year. Since I was so busy, I did not have a chance to send the statement/record after the 12th night stay. Thanks to their double night reward promotion, I will actually make it to platinum level next week, yipee!
