Hello!
I will share an itinerary with iconic and must-go places you should visit if you go to NY.
P.S. If I didn't include one place you want to visit, my advice is to add it in one day that you know you will be near it. My itinerary was made by zones, like that you're not spending the whole day moving everywhere.
I highly recommend you check the events available in the month you go because there are many and they are very good; for me, it was the best experience. I went in December and I had the opportunity to watch The Nutcracker.
I will leave some free time in the days, for you to include all the extra events you want to go to.
Enjoy your trip to NY!
