They could probably cut it to the 3 main days ( Christmas eve, Day & Boxing Day) and most would accept it and there's probably merit to that. It's about using common sense, very few will have big parties this year. I know my family certainly aren't having the normal things we normally do, or anything close. But if you try to deprive people of that hour or two on Christmas day with their parents, kids, grandkids etc, then I don't think people will comply at all, and it would actually encourage some to actually ramp up their Christmas plans i reckon.
