Hi
I will be at the party too and live here.
Come into JFK or LGA it does not matter I travel almost weekly, JFK is more organized.
The Hudson hotel or the Royalton (better the hudson) trust me there is nothing like make sure you get a nice size room not the regular one.
Also use

I stay in hotels in NYC some times for the weekend its nice.
The Hudson is not far from time square and all that stuff.
