I am one of those people who loves the Christmas season, and everything about it.
I always work my scheduled flying so that I can spend December traveling to one of my favorite cities. Last year it was London, this year it is Paris. That doesn't mean that I don't enjoy getting out to see my own city.
Downtown Dallas is living up to it's potential more each year. The window displays at Neiman Marcus are not only beautiful, they are interactive this year. Check it out here http://www.neimanmarcus.com/store/info/store.jhtml?storeId=01/DT
From Neiman's you can stroll down Main Street past the festive light displays to the large tree in Pegasus Plaza. I think that the perfect way to end the evening is with a warm drink on the top floor of Iron Cactus http://www.ironcactus.com/dallas.asp overlooking the downtown scene.
I usually start my own decorating the day after Halloween. Since I am not at home for about half of the month, I like to decorate early so that I have time to savor the season.
