Now, I'm not into Christmas at all.
I get what you mean. This year, I will be going through Christmas largely on my own because everyone is either travelling or too busy to catch up, but that's fine with me. Will go out for a walk, have a good meal, and get some exercise. Looking forward to see how it will turn out for me.
That sounds like a decent plan and the best use of the day considering your friends will be away.
