Face Coverings
Face coverings are optional for fully vaccinated Guests in both outdoor and indoor locations. We expect Guests who are not fully vaccinated to continue wearing face coverings in all indoor locations, including indoor attractions and theaters. Face coverings are still required by all Guests (ages 2 and up) on enclosed Disney transportation, including Disney buses, monorails, and Disney Skyliner.
