According to Pump It Up, air is essential for a successful rowdy romp. During three fun-filled open-bounce sessions, children leap around gargantuan air-filled bounce houses, skip down air-filled slides, and slither like legless snakes through an air-filled obstacle course, losing themselves in a world of multi-colored inflatamania. Pump It Up’s indoor air arena is climate-controlled and cleanly maintained according to rigorous guidelines set by a team of well-trained staff members. Parents play for free, so childless adults who want to play will need to borrow their neighbor’s kid or win one by collecting enough cereal-box tops. Open bounce times run during the day on Mondays and Fridays (10:30 a.m.–noon), and in the evening on Fridays and Sundays (5:30 p.m.–7 p.m.). Check the schedule and get ready to deck the walls with jolly bounces.
