If you mean like having a friend come and stay and hang in their room for the weekend? No. They will be able to visit on some weekends and hang out inside a 5 mile radius. Now, they could take pass and leave for the weekend, but there are limitations and rules, especially as a Plebe. They get more and more freedom as they progress through, but as far as I know they will never have non-Cadets hanging in their rooms (aside from official overnights for protective students, etc.). Apologies in advance if I misread the intent of the question.
