My boys ages 10 and 8 had a wonderful time at Steve & Kate's in Bethesda this summer. This is the only camp they don't want to go too late or leave too early. It's that much fun. They regularly bake bread (like bagettes from scratch with kosher salt - yum!), make music videos and leggo animation, play a variety of old school games, and best of all, besides their smiles at the end of the day, it's flexible for parents AND it includes a solid lunch and snacks. Success 2nd year in a row - they look forward to attending next year. The counselors are engaged and seem to enjoy being there. I can't tell you the relief it is to find a flexible camp that the kids love love love. At the end of the day, animation movies are emailed to parents. I can't recommend them enough.
