I'm a Christmas tree guy working nights. What should I do during the day?

UPDATE: Thank you everyone! Love these ideas. Having JG Melon tonight to kick off my NYC extravaganza and plan my next week of activities. You guys are great, happy holidays!

UPDATE 2: just kidding it's way too packed, maybe tomorrow!

Hey everyone! As title says I'm in the area for the month and want to get the most of my time while I'm here. Usually living out in VT and never spent any significant time in a city. Pretty much sleep all day from 9-3 once I get off my shift and then the afternoon/evening until about 8-9 is my time. Any suggestions are appreciated!
