Christmas Eve Midnight service.
I would skip any that start in the 7:00 pm range... these are usually focused more on the kids and often have a kids' play or skit re-enacting a version of the nativity. But if you go to an 11pm or later service (the "midnight" service) it is usually a serene candlelit service that becomes quite joyous at the very end. Very peaceful. I've never left a midnight service feeling rushed or sad or anything but joyous and peaceful.
