I've had a few this year, but I mostly just book suites when I want one. And on no SNAs (though I am hoping my SNAs get approved at JW San Antonio Hill Country later this week). I've gotten suites after booking basic rooms the last few months at the Renaissance OKC and the Ritz-Carlton Bachelor Gulch. I also got a spectacular upgraded room (because of the view and patio) at the Ritz-Carlton Half Moon Bay after booking on points.
