I have just made reservations for myself and my brother at The Jane in Manhattan for 4 nights starting on 12/30/13. It's a hostel with single rooms, bunk bed rooms and private rooms with bathroom. It gets a 4 star Trip Adviser rating from people who stayed there. I anticipate a fun, possibly cold, 4 days of bars and cafes and maybe a little comedy, music or theater.
Here is The Jane:

Would love to meet/go with some other San Diegans. Let me know.
