NYC Marathon.. help with logistics

Hi

I am doing the NYC Marathon this year. It will be my first marathon and I am absolutely pumped.

I have trained hard and I still have a ways to go, but I am confident that I will finish standing and smiling however, the one thing that I am struggling with is the logistics of it all so if any of you have done this race in the past, please, please help me out.

First, let me say that getting a hotel room for the night before just isn't in the budget... so that's out of the question.

I live on eastern Long Island, about a 1 hour drive (in normal conditions from Manhattan). My transportation assignment is : Midtown Manhattan (New York Public Library) at 5:00 AM.

So, what do I do?

Should I drive into Manhattan that morning (I'd probably have to leave my house at like 3:00am), park in a garage (if they're even open) near the library/

Should I drive to Staten Island and try to get as close to the race start as possible? But then I have to get back to Staten Island to get my car?

Should I take the LIRR into Penn Station (do trains even run that early?) on the day of the race?

AAAAAAAAAAAAAAAAAAAARRRRRRRRRRRRRRRRRGGGGGGGGGGHHHHHHHHH!!!!!!

I am stressing over this soooo much that I am thinking of it when I should be sleeping!
