Hey Karla,
Welcome to planDisney and thank you so much for your question! I'm so glad to hear you're adding a second day of fun to your trip, which will be here in just a few short weeks!
If you currently have a standard
1-day park ticket and want to add on an additional day then you should absolutely be able to do this. What you're describing is just a ticket upgrade! I did this on a recent trip where we also decided to add an additional day as well to make sure we had plenty of time to get in all the attractions we wanted without feeling too rushed.
What you'll need to do is call a helpful
Cast Member at the Tickets line who can let you know if your current tickets are upgrade eligible. Assuming that they are, you'll just need to pay the difference between your current ticket and the new ticket. Keep in mind that the new tickets must be equal to or greater in value than your current tickets.
Once you've done this, I like to also visit the
My Plans hub to make sure my
theme park reservations are all set and in place for the days of my visit. Additionally, this is a great place to make or manage any other reservations you might need for your trip like dining or enchanting extras.
Thanks again for your question, Karla! Have an amazing trip to the Happiest Place on Earth.
Have a Magical Day,
Greg
