Linking Disney accounts through the My Disney Experience (or "MyDisney") system allows families and travel groups to share and coordinate vacation plans in real-time. When you link with another guest via the "Family & Friends" list, you can see each other’s dining reservations, hotel stays, and theme park tickets. This is essential for modern park touring because it allows one person to book Virtual Queue entries or purchase Lightning Lane passes for the entire group simultaneously. Without linking, you would have to book separately, making it almost impossible to get the same return times for rides. Additionally, linking accounts enables "Photo Sharing," meaning that any pictures taken by PhotoPass photographers or on-ride cameras for anyone in the group will appear in the "Photos" gallery of the person who purchased the Memory Maker. Since 2025, the "MyDisney" login has also been unified across services, so your login for the Disney World app is the same as your login for Disney+ and ESPN, allowing for a more seamless digital experience across the entire Disney ecosystem.
