Hi Alejandra,
Welcome to planDisney! I hope you're having fun dreaming your Disney dreams and looking forward to all of the magic and fun you'll enjoy once you're at The Happiest Place on Earth! I'm excited
for you!
I'm happy to share that yes, you'll be able to upgrade your current
theme park tickets to the
California resident ticket offer that's currently available. The only caveat is that you won't be able to upgrade your ticket yourself online or by speaking with a Cast Member. You'll need to wait to upgrade your tickets once you arrive by visiting a Disneyland Resort ticketing booth and paying the difference between the tickets you currently have and the ones to which you'd like to upgrade. Please don't forget that you'll also need a
theme park reservation for each day you plan to be in the parks, so you'll need to wait until your ticket is upgraded to add that third day. I'd encourage you to make sure you check the
availability calendar before you upgrade just to make sure there's a day available when you'll be able to use that bonus day before those tickets expire on September 30th.
Thanks so much for bringing your question to us here at planDisney, Alejandra. I'm sending pixie dust that everything works out perfectly and you have a truly magical visit!
Missy
