Great suggestion by what you already mentioned and, Xmas365. They list can go on and on because there are so many out there. The really young ones (maybe the 10 year old) would probably like, Christmas Eve on Sesame Street. That is one of my very favorites. I watch that one alone even when the grandchildren are not here!
I have LOTS of favorites so the list can get really long, you might take a look at the list Xmas posted.
