Actually, it'll be five kids, cause Katie is coming too. Maybe six, cause Aden says that if Mav can take Katie, then he should be able to take someone. Not sure how they're going to enjoy having their knees around their ear holes if that situation arises, but it's not my problem. I'll be sitting in the front either way.
I was thinking about stopping at Gosford overnight the first night and aiming at being in Yass in the early arvo of the second day. We'll probably just see how the trip is going. If they were all bigger kids it'd probably be fine to keep going, but with the baby and a four year old (although he's a great traveller and is dying to get to Yass to muck about with his cousins), it might not work out. I'm planning on being pretty flexible with the travel times. I don't think it will work if we try to be too regimented.
