Pros:
Ethan Page is unapologetic about being a short course, keeping all but two holes under 200 feet. Every tee has at least one reasonable line to the basket, so experienced players need only putters. Even with the distances, hyzers, anhyzers, trees, and elevation changes come into play. I've played there half a dozen rounds and had a blast every time.
It's also welcoming to beginners, as most of the holes don't punish errant drives with nightmarish trips back to the fairway. It's forgiving, which helps when introducing new players. Good tee pads, good signage, quality baskets, and an easy enough walk that the groups I play with usually play through all 18 holes twice.
Cons:
The Par 2s? Why? They're not significantly shorter or easier than the Par 3s. Makes little difference for me, but no need to dishearten beginners.
Other Thoughts:
With the myriad of options Nashville offers, it's nice to have a change of pace and play an ace race where I can run every basket. My kids (three teenage sons) love it too. While I wouldn't want to play there every week, it's worth the drive (even knowing I won't need my drivers).
