Its interesting how you delineate "destination course". Being one who very much believes destination has everything to do with where one is and what is available while there (meaning one may be in town for a particular course and pick up on one or more others because they are convenient), out of curiosity, what is your definition of destination course?

Sean - a destination course would be a course that would inspire me to schedule a trip for the purpose of playing the course that involves an overnight stay. I do not mean a course that it is worth staying an extra night on an existing trip to enjoy.
I am willing to travel anywhere to play golf with a great group of people or for an interesting event, but the motivation for the trip would not be the golf course. If, on the other hand, I like the course enough that seeing the course itself makes it worth travel that requires an overnight stay independent of those other factors, I would consider it a destination course.
In my view, Palmetto is a destination course. Aiken would be an add on. Pennard and Porthcawl are desitnation courses. Southerdown is probably not although it is pretty close.
