Happy Play Day is a younger-child indoor playground built for ages 0-6, with a softer, calmer feel than a giant multilevel playground. The Westborough space focuses on open-ended play, toddler-and-preschool-friendly equipment, open play sessions, memberships, and private party rentals, making it a good fit for families who want a clean, little-kid-first option rather than a loud all-ages play warehouse.
