Research: 

Disney's Magic Express is a motor coach that picks up you and your luggage and takes you to your resort.   

"Disney's Magical Express transportation is a complimentary benefit available to Guests of select Disney Resort hotels. Resort Airline Check-In Service is also complimentary if you are staying at a select Disney Resort hotel and are also traveling on a participating airline."

"I’m taking a shuttle to an off-site hotel. Do I tip the driver?  You’ll see a sign at the front of the bus telling you that driver will accept tips. If you’re just hopping off and on the bus, you shouldn't feel obligated. However, if the driver is helping your store luggage under the bus, go by the dollar per bag rule. "
