I will be in Portland 12/9 - 12/14. I will be in training sessions for my job all day and was wondering what there is to do after 6:00pm on weeknights. I don't drink, so I'm not interested in the bar/club thing. I won't have a rental car so anything close to the Hilton Portland & Executive Tower would be great. As a second question, are the retail stores open in the evenings downtown or do they close early? Thanks!
