You can link two separate Disney accounts by using the "Family & Friends" list feature within the My Disney Experience (Walt Disney World) or the Disneyland app. While you cannot "merge" two accounts into one single login, linking allows different account holders to share plans, view each other's PhotoPass pictures, and make joint Genie+ or Lightning Lane selections. To do this, one person must send an invitation to the email address associated with the other person's account. Once the second person accepts the invite and chooses to "Share All Plans," both parties can see the same dining reservations and hotel stay details. This is essential for large families or groups traveling together in 2026, as it ensures that the person booking the 7:00 AM virtual queues can select everyone in the party simultaneously. If you have multiple accounts yourself (perhaps a legacy ESPN account and a new Disney+ login), Disney's "OneID" system usually attempts to sync these under one set of credentials, though linking remain the standard for separate individuals.
