Onyx I second the caravan park idea - depending on where you want to go, I've seen awesome Big 5 parks with crazy fun playgrounds in Queenscliff, Apollo Bay, Mount Gambier and all up the south coast of NSW. Google it.

We are off to Apollo Bay, to stay with my ILs in their beach house. Can't wait.

Even better, rumour has it the ILs are going to keep the kids for a few days after we come home! Wooo!
