Me again ! Good thing I've got this site

So I am currently advertising for a spot for Sept. I have 2 interviews scheduled for this week ... thing is none of them would be a GREAT match but I cant be to choosy in my area. So I have agreed to meet with them and see which family would work out best. One is a 4 going 5 year old B&A... which I would not really mind cause I am already going to be doing bus stop for my own child. The problem is they are not attending the same school so I would be waiting on 2 buses. I've never done this before so I intend to call the schools to see what time would the buses pick up and drop off. What else should I consider ? Could this be a problem ? I'm not sure. I will have 3-4 other children to take to the stop with us which is only at the end of my driveway and by then they will all be 18 months and over.

Anything you can think of ... please let me know.
