Crowd notes

Wednesday and Monday are often the best days to go for shorter queues, while Tuesday and Saturday tend to be the busiest. The most popular months are typically August, July and October, while January, December and February are normally quieter. To get the most out of your day we recommend arriving early and leaving late. Make sure to check the live queue times on our site throughout the day to stay ahead of the crowds.
