Mike,
I've played Teeth of the Dog and Puenta Espada each multiple times and could not disagree more with Mike Nuzzo's assessment.
Teeth is no doubt a wonderful course and most worthy of playing, though it is a several hour drive from Punta Cana. For years it was the gold standard for Caribbean golf. That was until Puenta Espada was unveiled 15 minutes from downtown Puenta Cana.
Both have gorgeous aesthetics, terrific seaside holes (though PE has a few more than TotD) and very good architecture. Each has a very different vibe. TotD has a more old school, laid back "down-country" feel and is set amidst beautiful villas and an airport landing strip. PE winds it's way around seaside villas and abuts some condo sites and is most definitely a high-end new resort. I felt the inland holes at PE weren't great, but the seaside holes were, on comparison, much stronger than TotD. Both will set you back real $$$, but are high-quality resort experiences.
Corales is also nearby Puenta Cana and pricey, but falls short on the architectural comparison. It is very well conditioned, has some very good Fazio oceanfront holes, but isn't, in its entirety up to Puenta Espada. It is also held out to be a highly-exclusive private course though available through most hotel concierges.
Roko-Ki, Faldo's effort 45 min away is now, I believe, NLE. Too bad, as it had a number of decent holes out there (a great finish) and lots of fun. Should it re-open anytime soon, it's definitely worth the ride.
