Hi! I actually asked Chef Gordon at Hilton Head about this, when we were doing the Private Affair dinner with him. He said that it's fairly difficult to host wedding events there, just because they can't close the clubhouse to DVC members, so I think that the wedding would have to be at strange times. There are certain legal restrictions that keep them from closing the member areas, but I think I remember he did say that you could do it after hours.
Cheers!
