"We're all going on a summer holiday....."

So yes, the plan is for DH and I to take the kids across on the Spirit of Tas on the day trip (kids will be nearly 4, nearly 2.5 and just turned 1) and stay in Melbourne that night and then start driving to the Sunshine Coast to spend Xmas with our families.

Soooo... I need some help puhhhleazzze....

We will be taking the shortest drive possible, so up the middle of Vic and NSW. We sorta plan to start driving at 7am, stop at 9am for breakfast for an hour, drive for 2 hours, stop at 12 for an hour for lunch, drive till 3, stop for an hour for a break/arvo tea, drive for 2 hours, and stay that night wherever we end up at 6pm. So however many days this would take us - apparently it takes 19 hours to drive? So we would cover approximately 8 hours of driving a day.

Can anyone help out and suggest good places to stop in for breakfast/lunch/rest breaks on the way through - or alternatively good accommodation that is very kid friendly and not that expensive?

All suggestions welcomed!

(oh, and wish us luck with 3 young kids in the car... bwahaha)
