Look at Christmas Eve Vesper service times ASAP. The earlier or later the service, the less crowded they tend to be. You can even call the church and see which service is less crowded. GET THERE EARLY! Christmas and Easter are the two days that most people go to church. Your regular seat will be filled, and the later you are, the more likely it is that you will be seated in a folding chair in the lobby. Find out if your church offers childcare for certain services. Enjoy the reason for the season.
