Nitty,
For some reason I thought you were already enrolling at Darden so I was surprised to see your post. If you can't find anyone to study with, I'd recommend going and studying in the Stern or CBS lounge. It's great motivation and really gives you a feel for the type of students. (Of course not every day but weekends are nice to get out of a NYC apartment,)
Of course you'll need to bare the typical GMAT bs...
"Man, I was so sick when I took the GMAT and I scored a 730."
"Man, I didn't study at all and still got a 710."
"Man, I went drinking the night before and was still legally drunk but got a 760."
"Man, I took a break and when I returned to my computer half of my verbal time was up and got a 720."
I think I'll use this one when people start talking about war wounds...
"Man, I had to take my test in brail because all the computers were already taken."
