When I tended bar in a hotel, I always had to work on Christmas. Hotels, of course, do not close on the holidays. They become large boxes of lonely people with no place to go except the hotel bar, hotel restaurant, or their own room. Every place else is closed on Christmas; sooner or later, they usually all wind up in the bar.
There is something sadistic about filling a hotel bar with Christmas decorations - reminding the customers of their isolation - by fate or design - from their families. It's like showing pictures of food to hungry children. Then you add alcohol to their misery and everything gets so much better. I think the decorations are nice enough in the two or three weeks preceding, but they might just as well be toned down a little out of respect on the Big Day.
One hotel I worked at tried to make me wear an elf hat on Christmas. I said, "I did not spend this much time doing my hair just to have it flattened out with a children's costume. No thank-you."
