Maybe look into the Camden,Rockland area of ME, might be worth a couple of days. State rd 1 about 1 hr south of Acadia.
Camden Hills State Park lots of shopping and outdoor activities in the area
Old Orchard Beach in southern ME your teens will like the beach, arcades and Amusement Parks. Tons of campgrounds in the area
