Fantastic place to go but if visiting in summer be prepared for long queues & some wet downpours! If you can get to the front gates for 8:30am they sometimes open a little earlier than advertised. This is great for those who want to get on some of the big popular rides without too much queuing! Other than that its only the on site hotels who have access before 9am. A wonderful experience that I would thoroughly recommend - remember comfy shoes too!
