Does this mean that drivers keep the same school holiday shift again?
What I mostly do is set out what routes I would like to catch for that day (we'll say 4,7,6,51,30) I'll then work out the timetables around them so that I have a few minutes in between. Of course it may not all work out (such as a recent one of mine when one bus was 15 minutes late) so then you check the timetables & see of you can catch your next route. You may end up an hour ahead of when you planned to finish or your buspedition was completely different to when you finished, but that's life.
