OK, OK, I TRULY appreciate all the comments, but I have to make a couple of points.
It is 9 days, not 7.
I will drop the long drive to Mach in favor of the ferry from Troon. Thanks.
I already decided to fly in a day early with my wife to see Edinburgh, and will suggest that to my group. (That also gets me to North Berwick a night earlier for a possible round before the others get in, but don't tell my wife that
)
I kept deleting North Berwick from my itinerary, but it kept working its way back in... It is the number one course I want to play in Scotland, and I could not justify replacing it with another course to save an hour of driving time. (Unless it was the Old Course, which can't be guaranteed.)
We cannot play Muirfield that week.
Two of the couples live outside of NYC, one outside of Philadelphia, one outside of Pittsburgh. You Scots don't know what a difficult drive is unless you've driven there on a regular basis!
I have been to Ireland three times and twice I did all the driving. This time we are hiring a driver.
I probably will drop Machrie in favor of Mach Dunes, because it seems rather expensive and time consuming to get there.
If I give the wives in this group a free day, I'm gonna be biking my ass off somewhere, or on a kayak on some damn firth ruining my golf swing muscles!
Anyway, thank you all for your comments and private messages!
