Well, at the Pontifical North American College: 8.
We took a field trip there with my class on Tuesday to see where the American priests study just steps away from the Vatican (and overlooking my street). There I noticed a contradiction in the elevator. The homemade sign outside the elevator said the limit capacity is 5 people. Inside the elevator, a plaque states the limit capacity is 8 persone. What’s the deal?
Our tour guide\priest cleared the confusion.
“8 persone italiane = 5 American men.”
