Its been 10 years since I played the Old Course, but the memories are still very vivid.
I'm surprised you were able to secure a hotel room at that venue. You'll be bumping into a lot of well heeled guests.
Good caddying is the most important part of playing that course. From the tee box and even approach shots, its difficult to see hazards or pin. Your line is a distant bush, church spire, or sometimes just a bump in a cloud. Then dial in the distance and shot shape. http://en.wikipedia.org/wiki/Old_Course_at_St_Andrews
Fly by wire and best wishes.
Enjoy a black and tan at the Jigger Inn and tell em Bagger said "A misst ye sae muckle!
