Hi Adriana!
Welcome to planDisney! Residents of Southern California and Baja California, with zip codes 90000-96199, and Northern Baja California residents within ZIP codes 21000-22999 were able to take part in the
California Resident Ticket offer this summer. Active from June to September, those eligible had the opportunity to enter the Disneyland Parks three times throughout a set time period. This ticket expired on September 15th.
Adriana, currently there are no promotions in place for Southern California Residents. We do not know if any special offers will be released in the near future. In the meantime, you can try and purchase a one-day ticket for your grandfather, so that he can take part in what promises to be a memorable trip. I checked the
Disney Park Pass reservation calendar to see if there are any parks available. Currently, only
Disney's California Adventure Park can be booked for the Tuesday of your trip. I suggest you hurry and purchase the ticket before both parks are sold out.
I truly hope this helps you plan a most magical Multi-generational trip to the
Happiest Place on Earth!
Malanie
