No, not every family member needs their own My Disney Experience account; in fact, it is much easier if one person acts as the "Lead Planner" and manages everyone. For children under 13, a parent must manage their profile. For adults and teens, you can simply create a "Managed Profile" for them within your own account by adding their name and age. This allows you to manage their tickets, Lightning Lane selections, and dining reservations all from one screen. However, in 2026, if you have tech-savvy teens or other adults who want to check wait times or use their own phones to mobile order food, they can create their own account and you can "Link" with them through the Friends & Family list. This "linking" ensures that you can still make group plans together while allowing them some digital autonomy. For a 2026 trip, keep it simple: have one person do the heavy lifting in the app to avoid the "linking errors" that can sometimes happen with multiple independent accounts.
