Big Air, Jacksonville

A 39-foot ninjasaur snarls in the corner of Big Air, bearing white fangs and a coiled, sloping tail that broadens to a two-lane slide. This inflatable monster shares a habitat with castles, volcanoes, and princess towers, as well as bouncy football fields and sports arenas. Together, these inflatables occupy a 12,000-square-foot arena that adjoins to a 1,700-square-foot "parent's space." As sock-footed kids frolic amidst the bounce houses and slides, parents enjoy grownup distractions such as free WiFi, pool tables, and novelty-sized checkbooks. Big Air welcomes guests for open play, field trips, and parties.
