Kidville - DC, Rockville

If Kidville were a real city, it would be pretty fun place to live—it's outfitted with a state-of-the-art tumbling gym and theater. Notably, each fixture is slightly shrunken to suit the city's denizens: kids ages six and younger. Tots are free to explore the gym during open play time, and learn in a more structured way during enrichment classes including gym, music, art, and more. Meanwhile, the facility hosts birthday parties with themes from dinosaurs to treasure hunting, a more fun party activity than waiting for treasure to hunt you.
