T.S.
Well... neither/both. The before and after program my son goes to is separate from the school, but it is NEXT DOOR to the school. So yeah, they "transport" him, but it's just the group of kids and teachers WALKING over together.
I like, that once he's at school, he isn't leaving (well not really) until I come get him. Also, if school gets canceled/dismissed early or anything, the daycare just gets him so there's no added logistical issue to work out.
