Crowd notes

Thursday and Monday are often the best days to go for shorter queues, while Saturday and Sunday tend to be the busiest. The most popular months are typically October, March and December, while January, August and June 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.
