I don't know that in my experience hosting hundreds of guests over the last 11 years never have I found anyone who needed to smoke inside. Yet, it's common, accepted and seemingly encouraged at the Sahara. The room wreaked. After showering I toweled off and noticed the towels also smelled of cigarettes' and then I did, too! We stayed at another non-hotel AIRBNB that was night and day, heads above this experience so this is hardly the norm in Las Vegas. There's usually a very long line to check in at the Sahara so expect to add an hour to your experience along with exhausted, perfunctory front office clerks.
