I don't know if this answers your question, but here's an example of a choice you could make.
Many on this site extol the virtues of Machrihanish, and it's well worth the long slog to get there. It's a great links course. About 10-15 miles south of Machrihanish is a funky, odd links course called Dunaverty. It plays at 4,800 yards, par 66. Cows roam over some of the course, it has a tiny, not-spiffy clubhouse, and no one would describe the course as manicured. But it's a true links course, with some outstanding views (Northern Ireland on a clear day), and a few truly terrific holes.
Some who make the trek to Machrihanish think it's nuts to take time away from playing another round there to spend time at Dunaverty, a course clearly not in the league of its famous neighbor. Nonetheless, Dunaverty offers the chance to play golf as many, many Scots play it -- not on a championship or even first-tier links course, but a good links on a piece of land that the local folks somehow managed to fit a course.
Your choice of courses, in part, depends on what you want to get out of your trip there. For me, personally, I went out of my way to find courses that were off the beaten path, a bit unconventional, and not populated by roaming tour groups of golfers. I didn't play on a lot championship courses, but I met a lot of great folks, and still managed to play a lot of fun golf.
