Just an update for anyone that is headed down to Myrtle. Brief reviews of the courses we played, ranked from best to worst:
Rivers Edge - Fantastic! Great layout, excellent shape, challenging and very scenic and picturesque - definitely my favorite of the trip
Cape Fear National - Awesome course. For a relatively new course, it looks very mature, and its in great condition. It was a good challenge, lots of sand and water to contend with. Extremely friendly and helpful staff.
Founders Club - very challenging as all holes are lined with waste bunkers instead of a cart path. If you don't keep it straight, you are in trouble every time off the tee. Enjoyable course that was in pretty decent shape. As others mentioned, there are better courses in the Pawley's area if you are going to make that long drive.
Carolina National - Great, challenging and scenic layout, but the course was not in very good shape at all. Some burnt out areas, some very patchy grass, especially in the rough and some of the greens were pretty beaten up.
Crow Creek - This course was in fantastic shape, and was very nice to look at, but we all found it to be very generic - Wide open fairways, a lot of hazards were out of play for a decent golfer. Also they double tee'd all day, so it was the slowest round we played. People down there really seem to love this course. If they tightened up the fairways and brought some more hazards into play off the tee it could be a great track.
