I didn't read everyones' replies, but here's a couple suggestions.. Handicap adjustments should take care of people playing from different tees. You may consider creating a red/white combo set of tees to shorten some of the longer holes and make them playable for everyone. The common formula for which tees to play is 36 times the distance of your average 5 iron. So if you hit your 5 iron 150, you should play a course around 5400 yards.
