As California theme parks gear up to reopen, the California Attractions and Parks Association is telling visitors "mitigate the effects of shouting" on roller coasters and other rides in order to prevent the spread of COVID. They go on to say that parks have the "ability to limit activities that are known to cause increased spread (e.g.: singing, shouting, heavy breathing."
Under the association's "responsible reopening plan" that was released in September, park officials can do so by requiring face masks and modifying the seating on rides.
Earlier this month, state officials announced theme parks, sports games and outdoor events could resume at limited capacity beginning April 1, provided the county the park resides in has reached the red tier in the state's reopening criteria.
Disney announced that after a yearlong closure due to the coronavirus pandemic, Disneyland and Disney California Adventure Park will reopen with limited capacity on April 30.
