I agree with Tony. The core ought to be a great nine hole course, ideally with alternate tees to provide variety and a couple 4.5 holes and at least one 3.5 which may be played as par 4/5 or par 3/4. Check out the harmongolf.com site: golf campus - course and campus layout. On 100 acres, there's a nine hole course plus a nine hole short course plus putting and chipping and bunker and wedge practice areas, heated driving bays on the full shot range, a fitness complex and a bar with a choice of draft on tap. Sounds like paradise to me. Also, I think the short course concept is more family friendly than a par 3 course as it is more enjoyable for beginners of all ages, while at the same time may be very, very enjoyable for the accompished player wanting to play at his or her short game.
