C&Js Party Rentals has something for everyone, be they the host of a corporate event, wedding, or kids’ party. DJs spin dance tunes or karaoke tracks while jazzing up events with lighting effects, and guests help themselves to offerings from margarita, snow-cone, popcorn, and hot-dog machines. For wee ones, the staff drops off trunks full of dress-up princess costumes, which they can don before entering an air-conditioned, interactive bounce house or obstacle course. To help parents relax, teams of costumed superheroes, magicians, face painters, and balloon artists arrive to entertain.
