We're having one on Monday with 10 priests. Apparently the priests here love these services, because they all come in from their rather scattered parishes, do the short service and hear confessions for about an hour or so, and then go out to dinner!
Beside I just love my Confessor. I still remember my first confession with him. I converted 3 years ago, and had over 52 years to talk to him about. He was a very patient man.
