Walt Disney World is currently requiring face masks for all guests visiting the theme parks, but like Universal Orlando, Disney will soon allow guests to wear face shields if they are unable to wear the mask all day and request accommodation.
Guests with disabilities who are unable to wear a mask may wear a face shield. Further details, like whether they will need to visit Guest Relations for additional clearance (Universal uses a wristband system for guests who opt for face shields) is still unknown. Either a face mask or a face shield is required to be worn at all times in the park. Many Cast Members are already required to wear face masks and face shields.
Certain attractions will require guests to remove the face shield and put on a mask, but the guest may wear the face shield in the queue before boarding. Guests utilizing this accommodation should ask Guest Relations which attractions require a mask instead of a shield.
