Tournament Golf....18 Hole Shotgun Start.....Time?

I think that for a charity event that most players would be attracted to the private club. If they want to play at the public course they can always go on their own. Private courses a seen as a treat to play and I'm sure that they can provide you with a good day. As for playing time you can expect something in the 5 1/2 hour range but a call to the pro will soon answer that question for you as I'm sure the club has done this before. Good luck with your event.
