Attendance at Disney theme parks was flat last year as it limited the number of people allowed in to improve the experience and faced tourism disruptions in Hong Kong. Visits jumped at Universal parks, driven by Harry Potter-themed rides.

A report by the Themed Entertainment Association and the Economics Practice at AECOM said that overall attendance at the 10 biggest theme park operators in the world grew by four percent last year and climbed to 521 million visits.

The report only looked at attendance in 2019 and didn’t take into account the disruptions in the industry this year caused by the spreading coronavirus, which forced parks to close for months at a time.

Parks that have re-opened are operating with limits on attendance so guests can maintain social distancing.

Attendance at the parks could be anywhere from a third to half of normal business volume.

The report said it may take one to several years to return to pre-COVID operating levels, and the investment horizon of many owners may be altered due to cash flow loss.

Attendance at Disney theme parks around the world fell less than 1 percent in 2019 from the previous year.

Disney is the largest theme park operator in the world by attendance.

Magic Kingdom at Walt Disney World in Florida kept its title as the world’s most visited park last year, with 20.9 million visits, a half percent increase over the previous year.

It was followed by Disneyland in California with 18.6 million visits, Tokyo Disneyland with 17.9 million visits and Tokyo DisneySea.

All of those parks were flat from the previous year.
