Its a terrific idea. Think about it:
The bus picks them in the dead of winter, its still dark outside, and its freezing cold. You could be greeted by a grumpy, unshaven guy (smelling of stale ciggarette smoke) who would rather be anywhere else but hauling a bunch of (equally) grumpy, unshaven teens, who would also rather be anywhere else, but on the bus.
Or they could be greeted by a cheerful, song filled “good morning!”, with the smell of spring in the air.
Which bus would you wake up for on time?
