We had a brilliant day. Got there for opening and went on the two big rides (Hyperspace Mountain and Grisly Gulch) straight away. They were excellent rides for me and my teenage daughter.The ticket booths open at 9am and the gates to Main Street open at 9:30am. The park itself opens at 10am. It was pretty quiet until just after lunch when the place became packed.If you don't mind splitting up, go in the singles line. You can get on a ride almost immediately rather than waiting for a long time in the queue. HK Disneyland has the same magical feel as Anaheim but it is smaller and there are less things for teenagers to enjoy. It seems a place more suited to families with younger kids.
