Moving to Pleasanton

Hello everyone! We are a family of four looking to move to Pleasanton in July this year. We have two kids aged 3 and 8 and am looking on advice on neighbourhoods that have kids that age? We are moving from a small town where all the kids would come outside and play with each other and I was hoping to find something similar. 

Ideally , we would like to avoid switching schools on our kids, so the plan is to find a good school in a wonderful neighbourhood. I hear all the elementary schools are great but any advice or help is definitely much appreciated.

My husbands job will be in San Jose, and I have heard that the commute can be horrid - any thoughts on that?

Thanks!
