Most modern hotels don't have an combustion devices in proximity to guest rooms. In that case it wouldn't be any more useful than a nerve gas or radiation detector... ie highly improbable. Typically the only risk would be central gas heat, if that, but that would have multiple safety systems at the central point. Even if code doesn't require it, insurance sure would. It's the odd-ball fly-by-night and third world joints where things could get weird.
I remember one place years ago that had a small gas water heater in the closet. I turned that all the way off at night.
