Linking parties in the My Disney Experience app is a high-fidelity requirement for coordinating Lightning Lane entries and dining reservations in 2026. To do this, open the app, go to "My Profile," and select "Family & Friends List." Scroll to the bottom and tap "Add a Guest." The most efficient high-fidelity method is to select "Scan Their Linking Code." Your friend can find their unique QR code under their own profile by tapping "Show My Linking Code." Once you scan it, your accounts are linked instantly. If you are not physically together, you can choose "Invite This Guest to Connect" and enter the email associated with their Disney account. Once they accept the invitation, you will be able to see each other's plans, including "High-Fidelity" hotel stays and park tickets, ensuring that your entire group can be managed as a single "High-Fidelity" unit for all virtual queues and bookings.
