To add a guest or link a pass in the My Disney Experience app, navigate to the "Family & Friends" section under the main menu. If you are a Cast Member or a Passholder with a "Main Entrance Pass," you must first ensure your own pass is linked to your profile via the "Memberships & Passes" tab. To add a guest to your party for a specific day, select "Add a Guest" and enter their name and age. If they already have a Disney account, you can "Scan their Linking Code" from their phone to connect instantly. It is important to note that for "Guest Passes" (often used by Disney employees), the passholder must typically assign the guest to their party before making a Park Pass reservation. Once linked, the guest's name will appear in your "Friends & Family" list, allowing you to include them in Lightning Lane bookings or virtual queues. Remember that Guest Passes themselves cannot be linked to a MagicBand; your guests will usually need a physical card or a MagicMobile digital pass on their own mobile device.
