Do you have a shuttle, to and from the Orange County/Santa Ana Airport to the Hotel and/or back?

Yes you can me and my family took one

You can have a bus but I'm not sure if you can have a shuttle. And you can take the bus to the hotel and back to the airport

Disneyland Resort Express The Disneyland Resort Express provides the most convenient mode of transportation between John Wayne Airport and the Disneyland Resort area, including Disneyland Resort and Anaheim Resort hotels. Upon exiting baggage claim, proceed to the GTC. The Disneyland Resort Express picks up Guests in front of the ticket booth located to the left on a regular basis. Reservations are not required, but there is a fee to ride.

I never see any of them when I'm at the airport
