Hi John,
As the only show on the island golf-wise, you're kind of stuck there. I remember it being pretty expensive.
I played it a few years ago, and the course doesn't really stick out in my mind good or bad.
The Devil's Triangle includes an awkward short par four with the green near the cliff, a great par three over the chasm, with huge cliffs, iguanas, etc., and a par five that I don't really remember. I think if you par all three (or tell them you did), you get a poster of the par three.
Regardless, have fun!
p.s. Order a few a Duffy's Love Shack for me...classic parking-lot bar down near the ferry to St. John with crazy drinks.
