My wife gets Hilton points through work. She hasn't been traveling lately, but she's got a bundle saved up, so we often stay at the Hilton Garden Inn or Embassy/Homewood Suites when we travel together.
By myself, I just get the cheapest local non-chain place I can find. The kind of place where all the rooms smell like cigarette smoke and where it's not unusual to see (or at least hear) a fight. I just look at it as free entertainment.
