I have experienced both climates:
For those who were raised in the northeast may not feel like it's not Xmas, because it is not cold. When you see a Xmas tree lighting, and it's eighty degrees outside.
My first Xmas tree lighting in TV, it was 80 degrees and it felt great. Everyone was in the spirit of Xmas. This seems, more preferable to "snow", and freezing one's butt off, as in Rockerfeller Center. It gets real cold in Manhattan, when it's windy and hitting you in the face, as it rounds the corners. I remember one year when you couldn't stand the cold, for more than an hour.
I too have my family in heaven, but I have a close cousin moving to Florida early next year and my son in Ft Lauderdale along with my granddaughter. I totally enjoy being with my family, and I will prefer it be, in the warmer climate.
Xmas in NY was really the best only because the whole family was living and together. I look back at those times fondly and longing that it that way just one more time.
BTW - I hate snow, except if I am watching a movie on television.
