Hello there, James! Welcome to planDisney!
I have some great news for you! The expiration date of the 2020 Southern California Resident Ticket has indeed been extended through December 16, 2021. You can use these tickets on consecutive or non-consecutive days with the exception of July 4 and November 20-27, as they are blocked out.
If they aren't already, be sure to link these tickets to your Disneyland Resort account so you can make
theme park reservations for each day you want to visit. Theme park reservations are required and limited, so be sure to check the theme park reservation availability calendar before planning your trip.
If you haven't visited the parks since they reopened, you will definitely want to visit
Avengers Campus in Disney California Adventure Park! This new area features some incredible food offerings, super character experiences, and a brand new attraction called
WEB SLINGERS: A Spider-Man Adventure. This attraction is currently only available by joining a virtual queue. You have the option of joining the virtual queue at 7:00 a.m. PST from home, your hotel room, or virtually anywhere. If you don't get a boarding group in the first wave, you can try again at 12:00 p.m. after you have entered the park.
I hope you have a great time at the Happiest Place on Earth!
