My golf highlight by far was having the whole year overseas right after college. I saw 172 courses that year, but I was also not on a schedule, so I was free to spend a couple of months in St. Andrews and a few days each at Dornoch, Ballybunion, Lahinch, North Berwick, and other places that caught my fancy. You do learn more about a great course the more you stay, or the more you go back, but some courses have far more to teach than others.
