I'd love to help you out, right now I'm only about 45 minutes outside of Times Square. But by this New Years I'll be far far away in VT.
If nobody steps up I would suggest looking at getting a room in Hoboken, NJ. From there you can catch the train into Manhattan and then work your way to TS.
Keep in mind it is not the same party as it used to be. Back in the day it was anything goes. Now it is crawling with Law Enforcement, check points and surveillance. If you end up going I would suggest you get to the TS area no later than 8/9pm. After that it may be difficult to get passed the barricades and searches.
If it were me I'd go to a New Years party with friends indoors so I could relax and enjoy myself and not worry about getting harassed, robbed or killed.
If I end up downtown at a party I'll give you a heads up.
