I am planning a trip to do Aconcagua Dec 26 - Jan 6 or so. I am buying my tickets this week. I don't have a partner and would love to have one, particularly someone fairly experienced with high elevation. I have been at 20,000 ft before and am training now for this adventure. If you are interested in joining, please message me or respond to this thread.

Did you go and did you find other people through this forum?
