Planning for Christmas is a big event in most households, but it seems that the Queen is more dedicated to keeping the spirit of the season alive than most others. The Royal Family retreat to their Sandringham Estate in Norfolk for the festive period, and Her Majesty oversees much of the preparations herself. She arrives in plenty of time to do it, too.
A full week before Christmas Day, the Queen will travel ahead of the rest of the family to Sandringham and commence planning for the events to come. Prince Charles and the Duchess of Cornwall are generally the last to arrive, making their own travel on Christmas Eve. It's a huge family occasion, which everybody is invited to. The Queen personally selects a tree each year (Christmas trees being a tradition started by her great-great-grandmother Queen Victoria), and decorating it is the responsibility of the children and grandchildren.
