I am not familiar with the after school program in Loudon and how good is is, but I will say that given this choice in Farifax county I would absolutely choose SACC. The SACC program at our school is wonderful. There are a wide variety of activities to choose from every day; gym games, playground, board/card games, crafts/art projects, our center has also done things like plays and talent shows. Unless your kid really loves the singe activity you sign them up for I can't imagine doing just one thing every day after school.
