Once we hit the 4th hole at a pace of 7 minute a hole, there was a duo who slowed our pace down to nearly 20 minutes a hole. When we hit the turn we saw three groups at the clubhouse, and the 10th hole was free. We stopped and asked the groups ahead waiting if we could play through. All said yes except the twosome. The last 9 took us nearly 3 hours and at one point there were 9 groups on two holes waiting for this twosome. Will not be playing again since there’s no marshaling on pace
