My Club's finishing hole is a Par 5 and it plays as a 3 strokes (unless you can carry 300 yds off the tee).
I would never like to see a finishin ghole as a Par 3. Played one nice course with a Par 3 18th hole and it was absolutely strange... din't like it at all (and it was a very short par 3)
I think Passatiempo finishes with a par 3.
It was different.
