I have played in Jamaica, but not at Couples. I played the Wyndam Rose Hall course, the one used by the Johnny Walker event. Pretty nice layout, some holes near the water and some up in the hills. It is am interesting experience. We were required to tke a caddy, even though we were also required to use carts!? It finally occured to us that he was there to negotiate with the locals to give us our golf balls back! A number of holes on that course have blind tee shots. You hit the ball and KNOW it is in the middle of the fairway but get over the hill and nothing. A few minutes later someone comes out of the woods or bushes and offers to sell you some used golf balls. Used all right, it is the ball you just hit!
Once you get past that the golf is pretty nice. Always warm and generally a bit windy.
