In my case, I can't tell if it affected my PLAT5 qualification or not, since I had well over 5 other nights to maintain anyway. I think this year I may even have enough to hit Plat without the help from Amex.
I've always wondered if they ever check that you charged your stays to the Amex, or if they just verify with Amex that you hold a valid Platinum card and post 5 stay credits on your profile.
The few times we called into FPC for the Plat5 promo, the attendant did put me on hold to check on the account with Loyalty. I believe FPC does check and verify if the reservations have been paid with Amex Platinum, but this was a few years ago.
