Walt Disney Co’s 2 theme parks in California are due to reopen on April 30 to a limited number of guests, the company announced on Wednesday, over a year after they closed to help curb the spread of COVID-19 infections.

Disney Chief Executive Bob Chapek said, on CNBC television, that attendance will initially be capped at almost 15% of capacity.

Advance reservations and a valid ticket will be required for entry. Guests will have to wear masks, observe social distancing measures and follow other safety instructions.

The Disneyland Resort in Anaheim, California, closed in mid-March of 2020. The resort includes the original Disneyland and the adjacent California Adventure theme parks.

Florida’s Walt Disney World reopened to visitors in July 2020 and Disney officials had been calling on the state of California to ease reopening restrictions.
