Well hello there, Donald. Welcome to planDisney!
If you have 
theme park tickets to the 
Walt Disney World Resort and want to link them to 
My Disney Experience, log into your MyDisney account and go to the 
linking page. Select "Tickets," input your Ticket ID, and follow the prompts. You can also do this through the 
My Disney Experience mobile app by clicking the 3 horizontal lines (☰) in the bottom right-hand corner, selecting "Link to Account," selecting "Type ID" on the upper right, and typing in your Ticket ID in the "ID Number" field under "Admission Media." If you run into any issues, I would recommend 
contacting a friendly Cast Member on the Existing Tickets line at the resort.
Since I see you're visiting pretty soon, might I recommend that you visit 
EPCOT on June 10th or later? Why? Well, that's the date that CommuniCore Hall and CommuniCore Plaza will be opening for the first time, completing the transformation of the center of this iconic park. Plus, "¡Celebración Encanto!” will be debuting on the CommiCore Plaza stage for the summer. An 
Encanto sing-along in the middle of 
World Celebration? Yes, please! Plus, there are a bunch of 
other exciting new offerings debuting across the resort on that date. It's certainly a great time to be visiting!
Donald, enjoy it all. If you have any other questions, 
I'm here to answer them for you.
The miracle is you,
Matt
