If they held it on the Mornington Peninsula, I doubt that there would be any issues of crowd control no matter which course they played it at.
If it is played at RM, it would be fantastic. And, no changes needed for match play, although the short downhill par 4 (where East meets West I think) could be played to the West course green, reducing congestion for the next hole heading East.
I fear (?hope) there might be a few Americans crossing the Pacific and 'rooting' for their team in 2011.
