A bouquet of balloons livens up any gathering, so it stands to reason that giant balloons would have an even bigger impact on festivities. Xtreme Energy Inflatables capitalizes on this idea by renting out its fleet of large inflatable structures and games. They deliver and set up slides, castle-shaped bounce houses, and cushy obstacle courses complete with tunnels and hills to all sorts of outdoor gatherings, from birthday parties to church and school celebrations. The company can also send out concession stands to feed guests, a safer way to foster a carnival vibe than turning a merry-go-round on its side and calling it a ferris wheel. The staff return at the end of the rental to deflate and repackage their wares. However, attendants can also remain onsite for the duration of the party for an additional fee.
