I grew up in Maryland and went to the Washington Waldorf School...don't know if that's the school you're looking at, or the Baltimore one. I can promise you that, if it's WWS, you can trust that they will be loving, caring, and do all that they can for your DD, should an emergency arise -- and until you could arrive.
Also, folks head to that school, and, I know, the Baltimore one, from far and wide, so there's a very good chance you could set up a carpool so the driving would not wear you out every day. I lived a half hour away from school and that just seemed normal to me -- that's how long you travel to get to school....it becomes routine.
Good luck with your choice! Write more questions about the specific school if you have them.
