How wrong were we? He had the time of his life... going to theme parks and eating. They went to the Tropical Fruit Farm, Sea World, Dreamworld and Movie World. He went on every ride twice and refused to leave the parks till closing time. The only one that they managed to leave earlier was Movie World and it was only because it was the last theme park they went to and he was too tired by then.
He told my parents that he wants to go to Sydney with his next school holidays. It's like "who needs Mum and Dad when I have Grandparents".
