We rented a 2BR villa at OKW with my parents, DH and DSs 3 and 8...Plenty of room!
See the DVC Renting/Trading Posts section on this site! You wont regret it!
Lowest season, lowest points would be September (or an equally DVC "value" season) for 22 points a night weeknights. They would need a two bedroom. Weekend points, or any other resort or time of year, will get more expensive. If they are willing to go Sun - Thur during the off season - DVC points could be a great option - otherwise its a budget buster for them.
For lots of space and truly affordable, you really can't beat offsite vacation homes for a large family.
