a royal queens christmas cast

I don't know if I would call it a "royal queens Christmas cast," but there are certainly some royals who play important roles in the holiday season. For example, Queen Elizabeth II of the United Kingdom traditionally delivers a Christmas message to her subjects, and Prince Charles and his wife, Camilla, often attend Christmas church services. In addition, other royals from around the world also celebrate Christmas in their own unique ways. So while it's not quite a "royal queens Christmas cast," there are certainly some royals who have a big impact on the holiday season.
