Thanks for all the responses so far. One follow-up (cut & pasted from his email....sorry to dump this on the DG, but he's not allowed to join the DG as a new member anymore)
"My friend has played the following courses: Royal Dornoch (several times), Nairn, Cruden Bay, Carnoustie (championship), St.Andrews Old and New (several times), Gullane courses, North Berwick, Muirfield, Prestwick (old), Western Gailes, Turnberry.
The question is not Dornoch vs. The Machrie, (of course Dornoch would win out).The actual question is: All things considered, accomodations, dining options, other sights to see, which would be a better use of time Islay and The Machrie or Kintyre and Machrihannish? we will probably be going there (i.e. Islay or Kintyre) from Ft. William, Port Appin or Inverness, not sure yet."
Also as a side bar, is Kingsbarns worth the money?, or for the money would you rather play and stay at Turnberry (considering my wife would love Turnberry? Decisions Decisions"
