"Please Keep Off The Grass," reads a sign above the turf at Inflatable Fun. Feel free to disregard that sign's instructions, because the staff here wants kids to explore every square inch of their indoor playground—including the turf. The play area features a dizzying variety of inflatable structures, from traditional bounce houses to an obstacle course equipped with a tunnel, slide, and minotaur cave. At the climbing wall, children don velcro-covered suits to aid them in their ascent, and an air-filled cushion makes for a soft landing. Older kids rack up high scores at the video-game station, while toddlers play safely with a pint-size playhouse and other age-appropriate toys. When it's time to break for lunch, parents can bring their own food or can choose from an wide range of snack items and coffees.
