ORLANDO, Fla. – 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, while visits jumped at Universal parks, driven by Harry Potter-themed rides, according to a new report released this month.The 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 4% last year and climbed to 521 million visits, according to the report.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.
