Hi Natalie,
Welcome to planDisney! I'm thrilled to hear that you not only have a Disneyland Resort adventure coming up soon but that you'll be able to stay and play even longer than planned! With so many
exciting experiences to enjoy this summer, you're going to have a BLAST!
Yes, you are always able to upgrade your theme park tickets as long as you have at least one day remaining on them. While you won't be able to upgrade them yourself online, you could try
calling a friendly Cast Member who specializes in tickets to add that additional day ahead of time or visit a ticketing booth or
Guest Relations location once you arrive at The Happiest Place on Earth. Just please don't forget that
theme park reservations are also required at this point for admission into the parks, so I'd encourage you to check the
availability calendar before upgrading your ticket to be sure that there's still room in the parks. Once that's all taken care of, though, you'll be enjoying even
more magic and fun! Hooray!
Thanks so much for stopping by planDisney, Natalie, and please know you're welcome anytime. I hope you have a truly magical Disneyland Resort adventure sometime soon!
Missy
