HEy Oliver,
I did Priceline last year in Febuary and got the Marriot Marquis for like 180 a night for 4 nights. I was pretty stoked. It is SUPEr nice and like right smack dab in the middle of times square. The subway station is right there too.
One thing in NYC< you dont want to skimp on the hotel or location. It goes from good to horrible real fast. I peeped out a hotel I was contemplating a previous trip last time, and I am so glad I did not trust the online pics! I used Epinion.com (http://www.epinion.com) for alot of resaerch. Hope this helps.
