I am just wondering if I booked two separate reservations for two consecutive nights at one property, is there a way I can get two separate stays (for FFN or stay credits)?

I guess if I checked it out and checked in again, that may be possible, but don't know for sure.

How about this? Make second reservation for both my wife and myself (or initially for my wife and then add my name to the reservation). Would it work?

How about priceline/hotwire reservations? I knew it depends on the property whether I can get stay credit or not. But, would two consecutive nights (with separate reservations) consider one stay?
