Station casinos Feast Buffet coupon

The Feast Buffet coupon indicates that the BOGO restricts to "cash paying" guests. Has anyone used their Boarding Pass points as the "cash"?

I have used the BOGO coupon at serveral properties and always used points for the balance.  I have never had a problem.  

Thanks!

we were in vegas in october and sante fe made us pay with cash when using the bogo coupon and a few days later at GVR they let us pay with points.

Thanks, Deborah
