Paul, with all due respect to Mr. Doak and with full love and admiration for all Aussies, well... the best course on this planet is in Mullen, Nebraska.
But the lure of Royal Melbourne is powerful.
I'm just not sure how logistically feasible it would be to play RM + the several other greats near it in the sandbelt area + the great new courses in Tasmania and NZ, all in one week.... Thus my willingness to add to Santa's gift on my own dime.
In any case, 7 days on the ground golf time in Scotland could be spent VERY well, and could easily include Royal Dornoch. You fly into Edinburgh, play whatever you wish around that area, move northward and play any or all of Royal Abderdeen, Cruden Bay, Nairn, Lossiemouth, etc... end up at Royal Dornoch, fly out of Inverness.
One could also make a great circle of Ireland in that time frame.
Kinda hard to have a BAD trip however one does this!
