I have 6 kids Mike.
We had a 2008 caravan and added a bench seat. Good vehicle, fit us all. No complaints really but we bought it used and the under rusted badly fast.
We replaced that with a 2008 Montana. Again nice vehicle. only fit 7 though so that sucked. Used it for abit with no issues.
Then we bought a 2011 chevy traverse and it is awesome! not a mini van but worth checking out. gets good mileage, all wheel drive, tow package, and it fits all of us.
Believe it or not it has more room then a mini van. fully loaded with 8 of us in we can still load in my sons hockey gear and get a few groceries
