Pump It Up in Sunnyvale is an indoor inflatable playarea for kids of all ages. Drop-in playtimes available during the week. Weekend primarily reserved for birthday parties.
We attended a birthday party here. I have to say, I was really impressed by the staff and how well they entertained and managed a large group of 4- and 5-year-olds. My son had a ball.
The place was really clean, and the party room was great for the kids. Nothing really stood out as different from any other bounce house place, really, but otherwise this is a fun place to go with energetic kids!
