Isn't Christmas just the best time of year!! All the festivities and spending time with your loved ones. Christmas in New York is quite spectacular, I have found that Americans really know how to celebrate the holidays. They go all out and Christmas here is magical.
If you are in the city for Christmas I would totally recommend you to try and see the 'Rockettes Christmas Spectacular'. It is phenomenal! From the dancing, singing, set design and the music it is quite a wonderful show to see. You will be in awe with all the detail that has gone into everything. If I am ever in New York again around Christmas I am definitely coming to see the show.
I have also made a video showing the windows at 'Saks Fifth Avenue' and some extras. I hope you enjoy it!
Merry Christmas!
