and btw - most of us dont refer to it by colored lines.
so if you ask where the blue line is, youll get a blank stare most times.
the A/C/E line (8th ave line) is being worked on during weekends. There is no C service.
www.mta.info is the best way. I suggest buying a whole day pass - forget what its called - unless you dont plan on taking the subway much. if youre taking it a lot its worth it.
You can also take the train to 50th (C/E lines only - A train on weekends) (hells kitchen) and theres tons of great restaurants (reasonable too) on 9th Avenue. HK is a great neighorhood. i live there so im biased. if youre ever confused on the direction - if you see a ton of lights its times square. go the opposite direction when headed to terminal 5.
and we're quite friendly. you can always ask. also - if youre weary of taking the subway at night - take a cab. its not too expensive. and its not hard to hail one.
btw - the subways are a mess EVERY weekend right now. i highly recommend checking out service changes depending where youre staying. i had one weekend where there were no trains stopping at 50th downtown. major clusterphuck but welcome to nyc and the subway. and walking gets us far!
if you have more questions about neighborhoods etc shoot me a PM.
