The manager at a Fairfield Inn told me I could become Platinum since I had >400,000 points. Is that true?
It may be a new wrinkle in the program but as far as I know the staying a total of 75 nights is a hard and fast rule to make Platinum in a given year.
If you host meetings there is also another way to make it. You can host meetings as shown here.
Good luck with the movement toward Platinum
Thanks; that's what I thought as well.
