I played a round of golf at Punta Cana's P.B. Dye course last summer. I found it to be a desert-like almost target-golf experience/layout in a seaside tropical setting.
As I had expected, the P.B. Dye aspect of it was overly contrived with bazaar landforms, an endless array of pot bunkers, stone walls, and multi-tiered greens. It didn't compliment the setting as it could have, and isn't a course worth traveling internationally to see. There is a Nicklaus course nearby, and a Fazio (and perhaps another Nicklaus) which were under construction and must be nearing completion. With those additions, it will become a more appealing golf destination.
We stayed at the Club Med - almost next door to the golf course - and there seemed to be an abundance of resorts of the all-inclusive variety in reasonably close proximity. The resort service was frustrating - friendly, but maddeningly lacking common sense, accuracy, or attention to detail found in finer domestic resorts.
It's probably a much better winter destination - Punta Cana in mid-June was HOT and HUMID like I have never experienced!!!
