I have to say, IMHO a DG company outing is not a great idea. Unless you work at a company that's all youngish athletic doods, most of the people are going to be hating it.
I play a course by where I work at lunch most days and have run across a few such company outings over the years, and I always laugh at how there is usually one group that is gung-ho and having fun while the rest of the groups are absolutely miserable.
It doesn't matter what kind of discs you get, that poor 50-ish, overweight, out of shape woman in accounting is going to chuck it straight into the wall of honeysuckle off the tee and there's no way in hell she's going to go in there and try to find it.
My advice... avoid having your fellow employees secretly hate you and set up a nice, relaxing company bocce tournament.
