Youngsters descend upon Rolly Pollies, engaging in active play furnished with age-appropriate classes and open-gym time while developing motor skills and social aptitude within the multihued, bustling space. Tots ages 6 months to walking can partake in the Caterpillars class, which gathers fledgling explorers for singing, games, and dissertations on the power of community. The Gymbugs class combines free play and creative arts to impart a well-rounded session of vibrant fun for 3- to 5-year-olds, and gymnastics teaches 4- to 7-year-olds how to master staying steady on the balance beam while simultaneously balancing their checkbooks.

The staff-supervised open-gym time sends energetic ingénues up to age 8 on a 90-minute jaunt throughout the gym’s varied play equipment. Tykes can practice tumbling skills, dive into the foam pit, scale the rock-climbing wall, or audition for NASA inside the moon bounce.
