Arrgh, I am close to getting 50 nights this year for platinum elite and counting every night. But somehow I missed ensuring my member number was added during my last hotel stay (4 nights). I thought it was strange I wasn't thanked for my status or offered breakfast/points, but I had been traveling for 20+ hrs and needed some sleep.

Anyway, it completely slipped my mind and now 2 days after checkout I just realized this.

Do I have any recourse?

Sorry if this has been posted before. I did some searching and couldn't find what I was looking for.
