I figured I'd start a thread on these because from reading her posts, Donna seems to say that Choice has a good program for getting free nights and it looks to be a lot more generous than Wyndham, which I have.
Wyndham Rewards - you get 10 points for every $USD you spend. Free nights start at 15000 points. So - if you stay at a lower end Wyndham such as Super 8, Microtel, or Knights Inn, it will take you around 25 stays to get a free night.
Anyone care to share details such as these about their programs?
