Walt Disney World Crowds & Wait Times for Saturday, December 18, 2021
How the Past Crowd Calendar is Calculated
My past crowd calendar is similar to other crowd calendars created for Walt Disney World. The crowd rank (1-10) is not actually based on the amount of people in the park, rather the average posted wait time of key attractions. Because Disney does not publicly disclose daily attendance figures, posted wait times are the best public indicator of how busy a park is.
What's a key attraction?
A key attraction is a major attraction that most guests visit. I do not take into account newer attractions as they don't have enough data and their waits are usually high and consistent day to day.
How is the average calculated?
The average is calculated from posted wait times during 10AM - 5PM daily, not including periods of downtime or when Disney does not report a wait.
How are the ranks calculated?
Each attraction has ranks generated on a 1-10 scale using daily averages before a specific date. Currently the scale is based on two separate periods (due to operational changes caused by the discontinuation of FastPass+):
March 2020 and Before: March 3, 2017 to April 30, 2019
July 2020 and Beyond: October 1, 2021 to March 31, 2022
Park ranks are generated from the average of that park's attraction ranks. This calculation method allows exceptionally high waits at a specific attraction to not outweigh the rest of the park. The overall resort level is the average of attraction ranks in all parks.
