Jace, space is always an issue. So is weight. Your rally-point is off campus- what is the drill for getting there? Everyone make their own way and if you aren't there in 30 they mark you as overdue? Or everyone que up and make your way orderly to the rp under the supervision of your instructors?

Teacher's kid here- I'm going to bet it is the latter. Under those circumstances, can you get to your locker? Can you be sure your locker is even there any more? That is the point I was trying to make. I talked with a family friend in southern California today, his kids describe it as a "line up, get out, don't screw around" drill. Can't imagine kids in private schools have a different plan- no time to hit your locker unless you happen to be in just the right place.
