if i don't die, or worse, i'm going to need a nap

Most people, when invited to a Saturday evening wedding in New York City, might make a weekend out of it.  Not me.  Now to be fair, until yesterday I was supposed to spend tomorrow riding roller coasters, but somebody (let's call him, oh I dunno.... D. San.  No, wait - Daby S.) fell down playing his hippie frisbee game a week ago and is still bitching and moaning about it like a little baby.  My original itinerary was to leave this morning around eight, and drive back home tonight after the reception - getting here around three or four in the morning.  I could get a couple hours of sleep, and nap in the car on the way down to Williamsburg.  It was to be a couple of long-ass days, for sure, but not completely unreasonable.  And ever since I talked myself into the ridiculous notion of making the wedding a day trip, it's been difficult to contemplate alternate courses of action.  Even considering my now-cancelled Sunday plans, I went to sleep yesterday thinking that I'd be back in my own bed the following night.

Now I don't know what to do.  I'm up way too early.  By which I mean: I'm up at the same time I usually wake up.  My plan hinged on sleeping in until about seven.  Under other circumstances, those two and a half hours might not matter.  But staring down a potential twenty hour day, those two and a half hours could be the difference between making it home safely or ending up in a ditch along the New Jersey Turnpike.  I suppose, should things go sideways, there is a hotel room available to me, but that brings up a whole nother mess of issues.  Like, what the hell would I do tomorrow?  Does anybody know if there's anything to do in Manhattan?
