Go to the 5 Drive in and catch a flick or 2. On Tuesdays it's $5 a person Thursdays is $15 a car, grab some snacks before hand and a blanket and pillows and cuddle in the backseat. Weeknights are usually less busy than weekends. Easily under $30 for movies (you can try a late night fast food dinner in the car as well if you'd like)
