2020’s attendance numbers are largely a function of regulatory agency restrictions limiting parks’ operating days and capacities and not park popularity and management during the COVID pandemic.
In 2019, the top 25 amusement/theme parks worldwide saw an attendance of 253.7 million. A -67.2% drop in 2020 saw only 83.3 million attendees worldwide at the top 25 parks.
