Tom:
My final comment on your original note, you realy got a lot of good input for asking about 1 course to play on one day!!! Whichever one you choose, you almost can't miss. I hope all goes well for the trip.
Big A:
If you don't go through a tour group, it's about a two year backlog to get on MUirfield. And if you attempt to go as a single, you'll be lucky to make it out of your car before being asked to leave.
