When Walt Disney-branded theme parks in the U.S. are open to the public once again, guests and employees will “likely” be required to wear face masks as the coronavirus crisis continues, according to the chief executive.

Disney CEO Bob Chapek speculated in a Monday interview that facial protection will probably be mandatory for parkgoers and cast members once Disney World in Orlando, Fla., and Disneyland in Anaheim, Calif., reopen for business.

Both iconic theme parks have been closed since March as a precautionary health and safety measure in the fight against COVID-19.

“Along with social distancing, one of the things we’re likely going to require is masks for both the cast and the guest,” Chapek told CNBC when asked what the most difficult aspects of ultimately reopening the American parks might be.

“In Asia, as you know, it’s fairly commonplace even before COVID for folks to walk around in public with masks on. That’s not the case in the U.S.,” he continued. “So that will be something that will be a little trying I think for some of the guests, particularly in the hot, humid summers we tend to have.”

Though a “limited number of shopping and dining experiences” will begin to return to service at Florida’s Disney Springs later this month, Chapek declined to comment on when Disney’s theme parks in the U.S. may reopen altogether.

"We're going to comment on any specific date to a certain extent. A large extent is going to depend on guidance we get from the federal government, state government, local government, [and] healthcare experts, as well as the immediate hospitals in the area of where we operate and where their capacities are,” Chapek said, further describing Disney Spring’s upcoming, limited reopening as a “good sign.”

The CEO added that he eagerly looks forward to the day that the theme parks can safely reopen.

“I get countless number of emails, correspondence from guests saying how much they can’t wait for us to open up, because to them it represents some semblance of normal, maybe the new norm,” he revealed. “We certainly want to open up as soon as we can across the world but we’re going to do so in a responsible way.”

“We’re excited for our guests, we're excited for our cast. We want to get our cast back to work as soon as possible,” Chapek continued. “It’s a first step, a baby step, but we're very encouraged by what we see in Shanghai.”
