Farming them out to Mears is much easier than trying to hire and keep full time bus drivers. The Orlando market is tough for hiring CDL holders. Disney is always paying a premium to get more bus drivers and Universal was having the same problem. Much easier to make it someone else's problem staffing the buses so they can concentrate on more important things. Mears runs all of the Disney Cruise Line and Magical Express buses so they have a huge pool of drivers available all the time.
