Supplying Western Massachusetts and Connecticut with floaty fortresses for more than a decade, K.E.C. Party Rentals stocks the area with inflatable castles, water slides, carnival games, and obstacle courses. Bouncers come in an inflatable rainbow of sizes, hues, and themes ($149.99–$349.99), with customizable motifs from favorite children's movies as well as combination bouncer-slides that allow kids to take gravity into their own tiny hands. Other air-filled arenas include the prismatic 40-foot Adrenaline Obstacle Course ($299.99 for up to six hours), and both dry and wet slides ($329.99–$499.99). K.E.C. also keeps easily bored partygoers from staging goodie bag riots with interactive carnival games such as Bingo Toss ($39.99), Giant Jenga ($49.99), and a Lucky Duck pond ($75).
