Disney also has many more better methods in place to "manage" daily capacity without deterring the customer. The amount of info magic bands alone provide is immense. Even more so the cell phone tracking info. via the app.
one example, for people with the disney app (which the majority do), currently they can/could instantly identify how many Disney users are driving down from out of state, or arriving at the airport by tracking cell phone location and determine who many to expect. That is just the tip of the iceberg of the tracking that can be done.
It is the main reason they are moving away from Magic Band to mobile phones. Much more data.
