I'd split between a value and a deluxe. Pop Century would be great for your kids, but would be a little cramped for a very long stay. I'd probably do it for 3 or 4 nights at the end of the trip (the kids might not want to leave if you did it at the beginning). The other 6 or 7 nights I'd stay at the Wilderness Lodge. Much more spacious, with great theming, and a fun interactive restaurant for the kids. You really can't go wrong at Disney though, so you'll be happy with anything you choose!
