I attended my friends' wedding here.
The Pinnacle has a nice grass area in which it conducts outdoor weddings. However, it is located adjacent to the outdoor bar/ dinning area of the club house restaurant. The outdoor space was not closed during the ceremony and noise carries easily over into the ceremony area. Thus, the noise from golfers and guests in the bar/dining area was somewhat disruptive during the ceremony. If I were planning a wedding here, I would insist the outdoor space be closed until after the ceremony.
Aside from that, the wedding was fine.
