Completely different suggestion: split into two teams of 4 and make it a team Ryder Cup style event. We did that with our 1st annual trip with 8 guys from Iowa and Texas when we met up in Tulsa last year. We did singles rounds, doubles rounds, and a round of team best shot to end it. We had to do the team event though because we had differing skill levels. It came down to the last team best shot round last year at the best course I've played,
The Lodge - Island Course. It was a blast doing it that way. There were 9 total rounds from a Thursday evening to Saturday.
