Crowd notes

Thursday and Wednesday are often the best days to go for shorter lines, while Saturday and Sunday tend to be the busiest. The most popular months are typically October, March and May, while January, June and July are normally quieter. To get the most out of your day we recommend arriving early and leaving late. Make sure to check the live wait times on our site throughout the day to stay ahead of the crowds.
