I'm sure this has been asked, but I can't find it. Does anyone have a link to Magical Express routes? What is the route with Art of Animation?
There is no link to a website with fixed routes because are no fixed routes for transportation from Orlando International Airport to the WDW resorts.
Disney's Magical Express coaches are loaded, dispatched, and routed based on actual demand.
As much as possible, the dispatcher tries to group resorts that are near each other. For example, the same coach often serves Saratoga Springs, Old Key West, and one of the Port Orleans resorts.
Some of the waiting queues at the airport list two or three resorts. Even then, there's no guarantee that a coach will go all of them. It all depends on where arriving passengers at that time have their reservations.
When it's less busy, such as late at night, the same coach could go to resorts that are nowhere near each other.
Don't confuse the letter codes on the luggage tags with transportation routes. Those codes, such as EC, are for luggage sorting and transport only, not for passenger routes.
