elaurensia,
I would add a section on the shuttle drivers.
Competent (includes drug-free)
Rested (includes records of time spent driving)
Retested for advanced driving skills
Etc...
Who makes sure the passengers are wearing their seat belts?
Would customers of other religions appreciate a prayer room?
Is there any need for a section on communicating with customers regarding timetables, pricing, cancelations, emergencies, etc?
