The one figure that doesn't make sense is Disney Hollywood studios. How can that small park do an average of 31000 guests a day and not go into near daily phase closure?This report is not supposed to account for hard-ticketed special events, park buyouts, after hours Halloween events etc., unless the event is included with regular admission. The point of the report is to try to put all parks on a level playing field for comparison sake. Magic Mornings while restricted to hotel guests would count since it is considered part of the regular operating day.
Why do you find it so hard to believe that Magic Kingdom averaged 57,000 people per day. That's an average. Some days are much higher and that means that other days have fewer guests. Park capacity is defined as how many guests the park can accommodate at any one time, but daily attendance is the number of unique guests who walked into that park at any time during the day. Most guests don't spend all day in the park, which allows the park to host more guests than the capacity is at any one time.
The only real numbers on there are Tokyo Disney (combined park attenance), Hong Kong Disneyland and Ocean Park in Hong Kong. Those were all reported publically. Disneyland Paris used to reveal attendance, but with full Walt Disney Company control now, it will stop.
