Was over charged full adult price for our 7 year old boy. We decided to go on a quiet weekday but arrived to find some blue light event where bus loads of kids were turning up and paying half price. We (three of us) went on the log flume twice and the mine cart once, which took a total of five hours queue time. Lots of kids pushing in line. Can't believe rainbows end tricked me into paying them $180 to waste my life standing in queues for half a day. Even my enthusiastic 7 year old gave up and said i just want to go home now. I gave feedback afterwards to their website contacts but they simply ignored me. I will never go back. The theme/water parks on the Gold Coast are much better.
