Royal Jump!, Arlington

Shrieks of laughter and the shuffle of sock-clad feet echo across the cavernous playroom at Royal Jump!, where tykes run freely through a lineup of cushy inflatables. The 45,000-square-foot floor houses 13 different structures, including a plush obstacle course, a double slide, enclosed bouncers for freeform leaping, and smaller areas where toddlers can flaunt their sharing skills in front of scouts from the big-kid leagues. In addition, Royal Jump! makes use of its spacious facility with four basketball hoops for kids to shoot on if they need a break. With much of the open facility visible from any vantage point, adult supervisors can keep track of their kids without sewing cowbells to their pockets. To help organize birthday celebrations, Royal Jump! arranges party packages that include a private party room, festive balloons, and disposable plates and plastic ware.
