Hi Mark,
Some water has passed under the bridge since I played at Sun City in 2000, but I have to say that I have fond memories of the experience. The architect who designed the course with Gary Player was Denis Griffiths from Atlanta, GA, USA. There is some nice elevation change, some good views and the greens were interesting. Perhaps the most interesting feature is the Crocodile (or Alligator???) pit next to one of the par 3 greens, but yes, I would suggest he play the course.
