I lived in Al Khor for around 6 months, it has most things that you need, for family life, however not a lot to do as there is a lack of things like play grounds, parks (except the Corniche), cinemas, specialty stores.

It is cheaper to live there, because of the high proportion of expat workers, from Asian locations, which is great for the budget, a bit dull and dingy looking, nothing like the DOHA skyline and facilities, has a friendly atmosphere from most of the locals..
