I see your idea Steph but doesn't planning two different Christmas meals avoid the point a little? I assumed the idea was to get everyone together for a celebration and having two meals would only split the groups up. IMO, if it was one meal people would be more likely to make the effort to change work/ other commitments to attend, where as with two meals people would be less interested and therefore the turnout would be even less. Thats the way I see it anyway, I'm probably wrong...
