It's very helpful when you have a large amount of kids that need dropping-off/picking-up times constantly, so having automatic schedules helps cut down on paper work.
Also, sometimes its difficult finding things like car seats in your vehicle during school hours if they are not located near where you park! Try using this program before purchasing; there may be better programs out now as well. Keeping track with multiple students all together can get confusing quickly. Having scheduled pickup and drop off times makes everything easier especially since we had quite a few kiddos who needed constant attention.
