I was there this summer, and it's a really nice place to play. I played on 3 golf courses over there
Teeth of the dog, incredible golf course, better that what i imagined, really one of world's golf wonders. It's quite far from most of the hotels, like 50 miles away from punta cana.
Punta Cana golf links, really nice too, whe can easily recognize Pete dye's signature there, green surrounded by water, and bunkers.
Cocotal golf club. Not well known, but i could play there free with my hotel pass. It's just ok, nothing exceptionnal, really easy courses , low slope. I played under par there.

Courses are fairly flat so they put a lot of water hazards and bunkers. Got to be used to Bermuda Grass too. High bounce wedges is nice too as conditions are smooth.
