The Disneyland Resort and Walt Disney World are once again going to require ALL visitors to wear masks regardless of vaccination status.
With the Delta variant spreading quickly and Covid numbers once again rising the theme parks website reads, "The State of California strongly recommends that all guests be fully vaccinated or receive a negative COVID-19 test prior to entering the Disneyland Resort. Beginning July 30, face coverings are required for all guests (ages 2 and up) while indoors, including on many attractions and in enclosed transportation vehicles regardless of vaccination status. Face coverings remain optional for all guests in outdoor common areas."
So if you plan on visiting the park soon, keep in mind masks are once again required indoors.
