Dorm rooms are crammed enough as it is without your roommate s significant other staying the night. The proposal does limit the time a guest can stay to 24 hours, but it means more bodies crammed into beds and bathrooms. This would be solved with a little communication between dorm-dwellers, but that is probably asking a lot.
Privacy is cut down even further.
Some have said having a member of the opposite sex roaming the halls at all hours of the night would make personal privacy virtually impossible. True, some dorms have community bathrooms and concern for prowlers would have to be considered. Of course, the same thing could happen under the current visitation policy. A peeping Tom or Tonya is the same at 4 p.m. or 4 a.m. There are many others to consider, but the bottom line is look at the big picture.
