We did it last year but took 5 days, we had our camper and set up just one section without the annex but if you follow the big4 caravan parks up they have great accommodation. We had a special bag of toys and books for the kids, the magnetic drawing boards were great and the DVD player came in handy too. We went inland and most places were great expect one park which was a tiny residential one outside of Newcastle we drove further than planned on the way home and mistimed the drive.
