By Hilton policy, smoking and vaping are prohibited in all DoubleTree properties, including but not limited to sleeping rooms, meeting areas, and the restaurant and bar. They are also prohibited outside in most areas close to the hotel entrances and air intakes. You can smoke or vape outside the ballroom entrance if you remain more than 25 feet from the doorway. The park across the street is available until it closes at midnight. Please remember there is no smoking at the TriMet station either.
