We had a combination ticket for Dream World and White Water World (which I would highly recommend - we also visited Sky Point which is included in the ticket). We spent a couple of hours at White Water World and had great fun. There were short queues and and we got to try each ride a couple of times. The wave pool was closed though which was a bit disappointing for the kids (teens). We went to Wet n Wild also during our holiday but agreed that we preferred White Water World - the water was warmer and more rides were open. It was also better value with the combo ticket we had. We went in Winter outside the school hols without wet suits. It was sunny so we were fine. Lockers available for 10 dollars. We enjoyed our trip, it was good fun.
