Hi Sangwon!
Welcome to planDisney! It is my pleasure to help you with your question about Southern California Resident tickets. Offered to guests of specific zip codes, the
Disneyland Southern California Resident Weekday Ticket provides for three visits to either the
Disneyland Park or
Disney's California Adventure Park from January through May. Admission is solely Monday through Friday, and Saturday and Sunday are not permitted. Proof of residency via government-issued photo I.D. is required.
While the SoCal ticket offer is popular, it is only available during the January through May season. Historically, the offer has not been extended for later months, so it is not known at this time if a summer-type ticket will be offered. My best suggestion for you is to keep an eye on the
Disney Parks Blog for any announcement about the extension of, or future offer for, Southern California Resident tickets.
I hope this helps you plan a most magical vacation to the Happiest Place on Earth!
Malanie
