Low balcony railings pose a little-known but deadly risk in some resort hotels. In the past several years more than 50 Americans and Canadians reportedly have fallen to their deaths from hotel balconies whose railings were lower than permitted by U.S. safety standards. Incidents have occurred in Cancun, Mazatlan and Puerto Vallarta, but could occur almost anywhere. Just as you should check for emergency escape routes when you arrive at your room, you should also check your balcony so you are aware of any danger.
