That's exactly my plan based on the research I've done. Obviously it's still far out and the length of the trip is TBD, but I was thinking 10ish days split between St Andrews and Inverness (hopefully being able to use the Inverness airport for one leg of the trip). If we expand to 2 weeks, would probably throw Aberdeen/Northeast Coast into the mix on the way between the two. Hiring a luxury van to do all transportation, and setting up shop in each area to allow us to explore and not be on a regimented schedule would be ideal.
For St. Andrews, obviously I'll want to play the Old Course (with all the tee time challenges) but Kingsbarns, Crail, Carnoustie, The New Course, Jubiliee, and even a local spot like Leven Links or something similar would be a blast. Then in Inverness, Royal Dornoch, Castle Stuart, and Nairn are must plays (I think) but I'm always open to suggestions. Plus then we get to sample the local pubs and explore the areas a bit, while having flexibility to adjust if we decide we want to replay courses or duck over to a distillery.
It's exciting to think about, no matter how far away it is.
Sounds good. A nickel's worth of free advice about your choice of courses, granting that you're still a long time from any of this becoming real:
--For the St. Andrews leg, definitely play the Old Course (if you can), the New Course, Kingsbarns and Carnoustie (which is not at all a personal favorite but still worth having on the bucket list). After that, I would give the Jubilee Course a miss, which is just a harder and inferior version of the New Course. Crail (Balcomie) is fine but rather quirky; I prefer both Elie and Lundin Links to Crail, and strongly prefer them to Leven (and the Jubilee, or Crail-Craighead which should definitely not be on your list). Panmure, near Carnoustie, is also a very good alternative. And it's about 90-100 minutes from St. Andrews to my neck of the woods (Muirfield, Gullane, North Berwick and Dunbar), if you want to do one of those as a day trip.
--From Inverness, there are a ton of fun courses within reach. Dornoch is probably my favorite course in Scotland, non-Old Course division; it and Castle Stuart are definites. Nairn is good, but it also has lots of gorse on both sides of many fairways, and there are many holes with no obvious bail-out options, so if you've got a lot of high handicappers, I'd consider going elsewhere. Lossiemouth, a little beyond Nairn, is stern but solid and slightly more user-friendly than Nairn. The one other course around Dornoch really worth seeing is Brora, a really fun but also well-designed links with a back-of-beyond charm all of its own (e.g., it has electric fences around the greens to keep the sheep away). Golspie is another fun and quiet mishmash of links and parkland golf near Dornoch. Other people vouch for Tain (which I played once, a long time ago) and Fortrose & Rosemarkie as other quaint options nearer to Inverness than Brora or Golspie, but I can't call myself an expert about either of them. If you want a non-links option during your trip, Boat of Garten - south of Inverness - is also full of character, and probably unlike any inland course you've seen.
--One other point I've made before: most of these clubs have Open Competitions that anyone with a formal handicap can enter, even an American handicap. If you really want to go to town, schedule your trip around one of these competitions and get everyone to enter it - and see what *real*, competitive Scottish golf is all about. (Every club will list its schedule of Open Competitions on their website, and the dates rarely change from year to year.)
Oh, I've got plenty more where all of this came from as well...
