Pump It Up, Rancho Cucamonga

Voted No. 4 in the Top 10 Birthday Chains for Kid Birthday Parties in 2010 by Parents magazine, Pump It Up pulses with inflatable play sets and actually encourages kids to bounce off the walls. Within the indoor playground, a stalwart staff oversees the neighborhood of bounce houses and air-filled playthings, such as a classic bounce castle and slick inflatable slide that cushions children's heartfelt reenactments of Cool Runnings. Throughout the week, families can pop in for open jump sessions or tote along their own mini entourage for birthday-party packages complete with private rooms and complimentary invites. Parties come as straightforward packages or as themed events that place the birthday child in structured story adventures where they take on the role of a mighty and clever superhero or pirate captain that drank too much salt water.
