I'm interested in learning more about your math. Before I left the US last year, I was hooked on gaming hotel programs, but since I tend avoid western chains in China (if I do a chain at all, it's Shangri-la because I'm usually guaranteed a nice hamburger... but, a crappy rewards program), I've fallen out of the loop.

In short, I'd like to pick your brain, but please hold the fine points close to your belt for the sake of the deal's survival.
