When we were looking for a course near our potential retirement place (Chapel Hill, NC), we tried several courses. When we played Hope Valley, halfway through the round I told my wife that "this is a course I could play every day." The initial reaction was based on the quality of the routing, the condition of the course (especially tees and greens), the variety of holes/shots, the fact that it is challenging but does not beat the crap out of you, the aesthetics of both the course and the clubhouse, walkability, and pace of play. Since we actually joined a year or so ago, the initial reaction has been reinforced by the friendliness/helpfulness of the golf staff (even as non-resident members, we are greeted as regulars) and the flexibility in arranging tee times (teeing off on back nine available even on weekend mornings for a quick 9 holes). I do not know whether it is ranked on the Doak scale, but I guess it would be around a 5-6.
Then again, one of reasons Chapel Hill is appealing for retirement is that it is a short trip to Pine Needles and Mid Pines which as documented repeatedly on GCA are courses that could be played with great pleasure and enthusiasm every day.
And if all of the above sounds as if we just are Ross nuts, the one course--even though I have played it only once-- that if it were convenient that I know that I would absolutely want to play every day is Lahinch. Other than perhaps number 18, there is not one hole that is even close to pedestrian, and the other 17 are either excellent, scenic, and/or unique. As far as I know, the stretch from number 3 through 6 exists nowhere else in the world.
