There never were any South Carolina resorts owned by Worldmark the Club. What you saw was the result of an agreement between the two clubs to make a little of the Club Wyndham inventory available to Worldmark and vice versa
That agreement is dead. Replaced by an inter club exchange program called Club Wyndham Pass
As I said I'm not really paying attention whenever I looked on-line. Those must be an agreement before between two clubs. Hard to tell. Will see by June if it is really beneficial to all of us.
