The use of 3rd party contract buses has been an interesting sight due to the shortage of Disney bus drivers. Disney knows their staffing shortages and appeared to have had no plan to work
And we had an experience with one of these buses that was interesting. My Nephew left his expensive phone charger on the bus on the way to AK. The next morning while waiting for a bus to MK he saw the same bus - it was very recognizable. He walk over to the driver and asked if anyone had turned in a phone charger and described it. The driver pulled the charger out of his pocket. Even the auxiliary services are bringing the Disney Magic.
