My wife and I went to a 9 hole par 3 with the kids. It was a LOT of fun, i forgot to keep score after the 3rd hole though lol. We were done in just over 90 minutes.
A couple of things, we let one pair play through, but there was still a pair right behind us. We were not slow playing by any means, but I don't think they allowed enough time between our foursome (with 2 kids) and the people behind. The guy would just stand at the tee box and glare. He waited on maybe 2 holes for 3-4 minutes. It was irritating trying to rush play.
At what point would you ask him to play through?
A couple of rules we played by.. Best ball until the green. Maximum double bogey. If you don't get it in 5, pick up the ball.
