Ok! So... the arcade in providence could be a suggestion. Maybe some of the mills the decorate? Also... many churches in Newport and providence decorate and would take a donation and welcome it. Alot of college historical buildings would allow it. Think salve (ochre court etc), im not sure the athenaeum still decorates but that is a possibility. The John brown house decorates and takes donations. These are just right off the top of my head. Im sure I can come up with more when I'm not right off work and brain dead. I'll see what I can get to spark.
