Idea's for a 3 yr old B-day party???

We have a place in our town that you can rent that has a room full of blow ups full of ball like at McDonalds and all types of small toys for the littel ones and the kids have a blast. maybe your town has this or a place you could rent them.

My son will be 3 in August so I have a bit of time to think about this one. But for his second birthday we had a Cars theme. We went with the Pixar Movie - but you could aslo go with Nascar, toy cars, etc... You could also do a Deigo (from Dora) Party or Backyardigains.
