Julian: If "Royal Dornoch et al." includes Castle Stuart, go for the North Berwick/Gullane combination while further south. Kingsbarns and Castle Stuart are both modern-day, broad-shouldered links envisioned and developed by the same person (Mark Parsinen, who worked with architect Kyle Phillips on the former and Gil Hanse on the latter), and both cost more to play than most of the other Scottish courses (hence the "resort" feel referred to by Sean). To be fair, I haven't played Kingsbarns, but Castle Stuart--even in an unrelenting 40-mph wind--was spectacular. My point is simply that playing both (assuming, again, that you even plan to play Castle Stuart) might be somewhat redundant. You'll have an amazing time no matter which combination you choose. Enjoy, and try your best to include Brora while in the Highlands.
