Guests are welcome to visit their hosts as long as all roommates agree upon the length of the visit and the guest does not stay for more than three nights in any fourteen-day period. Visitation periods may be held in all College residential facilities during those hours established by each floor or section. During those periods, guests of either sex may visit individual rooms and lounges. All students are expected to observe the hours applicable to each floor or section and to individually support the visitation policy. In addition, all buildings have the option of adopting an escort system whereby a resident must escort visitors who are in the building.
