Hello Dana!
Welcome to planDisney! You are in luck, Dana! It's possible to upgrade your existing Park tickets to include the
Park Hopper Option!
All you need to do is log into your
My Disney Experience Account and look at your upcoming plans. Scroll down till you see My Plans, Reservations and Tickets. Right underneath it you will see Tickets, Passes & Memory Maker, and if you click that you will see the tickets you purchased and a link labeled "Change Ticket." It is through this path that you will be able to upgrade your ticket. There will be a price difference but there will be an option to pay when you finalize the changes.
Don't forget that right now you can't Park Hop until 2 PM and only until you use the
theme park reservation for the first Park of the day. Walt Disney World's fine print does say that the Park Hopper hours could start earlier in the day and it's important to keep checking the
Park Hours Calendar. How exciting if you can enter your second Park even sooner!
You are arriving during the
EPCOT International Food & Wine Festival! Having the ability to Park Hop to EPCOT to grab a delicious item from one of the nearly 30
Global Marketplaces sounds like a perfect way to end the day. Check out the
Foodie Guide for this year's festival and while one of the "hottest" items this year is the Pickle Milk Shake don't feel pressured to try it. I would rather enjoy Emile's Fromage Montage which is an ode to cheese that I can respect. Pickles with milk just sounds dubious to me.
I hope this helps and if you have any more questions please feel free to come back!
Happy Planning!
