Coach USA is shutting down their bus operations between John Wayne and LAX airports January 7th. Supershuttle will also be ceasing operations at the end of this year as both of those companies have filed for bankruptcy.
To get to and from the resort from those airports you must now rent a car or take an Uber/Lyft. This will mean it could be a bit more inconvenient for your next Disney trip if you plan to fly in to the state. Also of note is that if you choose the rent a car option, you will be paying unnecessary overnight parking fees at the Disneyland Hotels and surrounding hotels when you will not be using the car at all during your stay. My suggestion is to rent a car after your Disney trip if you are traveling to other Los Angeles or California landmarks during your stay.
