Visiting hours tend to hurt students more than schools may know.
It's three o'clock in the morning. If you're a fellow student living on campus at my school, you know what that means: all dorm visitors have to go. At our university, those visiting the dorms after six in the evening must be signed in by their host and, eventually, signed out by three o'clock in the morning. If the host fails to sign out their guest by that time (or fails to sign them out in general), they'll receive warning notices. After receiving multiple warnings, they'll be fined.
