After logging only a few nights a year the last few years, I have increased travel significantly this year and will make Platinum. After about 25 nights in 3 months, I emailed Marriott asking for a challenge. I was given instant Gold status with a challenge to stay 12 nights in the next three months to "keep" the Gold status. Otherwise my account will revert to Silver. I was very happy with how it was handled and have been enjoying the lounge access.
