joel:
since casa de campo and punta cana are pretty far apart, to which (general) location would you head first?
I'm no expert, and others who live/work down there might have a more informed opinion.
That said, Casa de Campo is the "Grandaddy" of golf in the DR (and the Caribbean in general) and you have the 3 GC's at the resort, access to La Romana CC next door, and La Estancia just 10--15 minutes away.
On the other had, the Punta Cana area (about 90 minutes from Casa de Campo as I recall) Has the excellent Punta Espada, the OK La Cana, Corales, which is supposedly really good, and Roko Ki, maybe 40 minutes away.
So--You have 5 golf options at Casa de Campo, including two really good ones (Teeth and Dye Fore) and four options at Punta Cana, with 3 great choices in Punta Espada at Cap Cana, Roko Ki and the new Corales course at Punta Cana. But--who knows how long Roko Ki will stay open?
