Ed, sorry to report that I had a great day of golf at the Valley course but sans camera. It is a terrific course that your group will enjoy very much. It is indeed down in a valley below the Dunluce course, with a very intimate feel and routing.
Speaking of the Dunluce, hopefully you will have time to get over the the castle of the same name and the Giants Causeway too. Great golf and sightseeing in Northern Ireland!
You can make out a couple of holes on the Portrush course from the Dunluce Castle, very cool.
