They had "Merry Member Mixers" last December that were held right near the International Gateway entrance to EPCOT. I don't remember how early in December they started, but we went sometime around the 22nd.
They had cookies and cider, character photo opportunities, a raffle for a big basket of
DVC goodies, a pin display/trading area (not sure how that worked) and they gave everyone who attended a silver DVC keyring. Nice way to spend an hour or so.
