Hi! I was recently in Manhattan and I stayed at the Wellington. It was clean and right off central park and I think it was $95. This was in January but if you go to orbitz or Expedia I am sure you can fi d something reasonable and u can see everyone's reviews. The rooms were small but it was okay since I was only there one night and it was one block to the subway. Not sure how close to Cornell though. Good luck with everything!
