An english-only golf magazine/newspaper wouldn't cut it in DR. Nor would an english-only newspaper. Various tourist areas put out their own little tourist booklets in english - - POP and Samana. These are guides supported by ad revenue from local resorts, shops, bars, eateries, etc.
For me a big question would be - - do english-speaking tourists actually travel to the DR to play golf? Or is playing golf just an extra-added - - i.e. let's got for the sun and the beach and relaxation . . and, oh look, we can play some golf too.
I'm not a big golfer but I'm also wondering if there are really enough world-class golf courses in DR to support a golf-centered pub. Are there any major tourneys in DR? Any ex-tour pros? I could see a website that sorts/organizes/describes golf sites in the DR - - with a booking business attached.
A golf-only pub might work if you broadened it a bit to something like golf in the Caribeann?
