As every year, some members have received "thank you" offers that help them extending platinum status by staying 20 nights between October 1 and December 31. Is there any logic as to how you get this offer? Any chance of asking the Marriott Rewards team to get this offer as well?
I think its called the, "Platinum Challenge", and you get it when you are close to making Platinum, but didn't quite get there, and are given a grace period to earn additoinal nites. I don't know if its the exact delta difference, or just a reasonable amount.
I have no further information on it, other than I received a couple myself when I stopped traveling as frequently. Often I was between levels, not clearly close to either, so was more than likely given the opportunity to gain the next level rather than being set back tot he last level.
