We used to do the Christmas display in the basement since my father was pretty much living in the living room (he was unable to walk in his later years). This year, after over a decade of having Christmas parties in the basement, we moved it up to the living room and decorated the entire house. This made things easier for my mother who’s task was to feed the huddled masses and she did not have to go up and down the steps to do that. This was my mothers last Christmas I believe.
The Christmas party went well and everyone had a good time. While having the decorations upstairs did not have the same atmosphere as having it in the basement, it was much more convenient for everyone since the bathrooms, kitchens, cable televisions, etc are all upstairs.
