Hi all, First time to DW this Saturday, going as a couple in the twenties. I am wondering how I can better organise the day. 1. Is the 10$ early entry worth it? Are all the rides available for early entry? 2. We will be staying in Brisbane, driving on rent car, when should we aim to arrive? 3. Is Q4U worth it? How many extra rides can it give for a day? 4. We will need the bag for stuff like sun glasses, camera, drink bottle, obviously can't bring them on the big rides, how are bags handled? Is there a place to store them before a ride? cost? locked? 5. Can you bring wallet, cellphone, glasses and jewlery on the big rides? Thanks In Advanced for all replies
