Hi there Barbara,
Welcome to planDisney! We're so glad you stopped by with your question - especially with one so relatable!
I have had to upgrade my
theme park tickets on a number of occasions for trips where we realized we wanted more time to see and do everything that we wanted. Luckily, it's a pretty easy process to upgrade standard theme park tickets to add a day to your trip!
The way to do this is by
calling a Cast Member at the Tickets line who can determine if your tickets are eligible to upgrade and, if so, will walk you through that process. Note that in order to upgrade your tickets, your new tickets need to be equal or greater in value than your current ones.
I'll also add that there may be certain types of tickets and special offers - like the
Southern California Resident Ticket Offer - where upgrading to add another day is not possible at the special offer price. In that case, you may be eligible to upgrade to standard theme park tickets to add that extra day, but again would need to confirm the specific details with a Cast Member at the Tickets line.
Thanks again for your question, Barbara! I hope you have a fantastic four days at the Happiest Place on Earth.
Have a Magical Day,
Greg
