We used to stop there all the time while driving through to northern Indiana.

The hotel shows a little age/wear, but is still nice. In addition to golf, they have a mini golf course, horseback riding, and a lot else in addition to having Mammoth Cave nearby.
Although very reasonably priced, it IS more of a "family" atmosphere, however. I'm not sure if it is exactly what a group of guys might be looking for.
