I'm currently a Gold. Called the MR line and asked what they had for a Plat challenge. I was offered 9 stays within 3 months, and Plat status not given until after the challenge was successfully completed. Not bad but since my travel is 1-2 weeks per stay, I will be earning Plat the old fashioned way this spring. I asked if they could do anything based on nights and not stays, but they said no. No sense in pushing the issue.
