Parti Palooza is basically an indoor bouncy house place in Livermore. It is great for rainy days and too hot days. I was just about thinking my oldest was growing out of it, but then they recently added a second room with kid sized bowling and a rock climbing wall!! A few arcade games, but not enough to give you a headache. They also have a karaoke room with kids songs and dress up stuff. Bring a book, because you won't see your kids for two hours!!!
A few things I like:
*They do multi age play times. At Pump It Up, my kids can never go play at the same time because they do it by age.
*They do drop off evenings where you and your partner can go to a movie or go out to dinner and know that your kids are having a great time!
*You can pay for just the bouncy houses or for both rooms, depending on your kids
Try it - you'll love it!!
