Good idea with the windows, Kristen. Actually, I had a friend in a similar situation to yours, Freddie, who took down all the curtains in the house and just left the blinds up for the whole weekend, then put the (clean and odor-free) curtains back up about an hour before her parents came home. Sure it was a lot of work, but if the smell of our clothes was any indication, that was the smartest thing she's done in her life.
