March down West side to Chambers

I'm trying to think of what it'll mean that a quarter of a million protestors are going to march from midtown, down West Street/Esplanade and all end up on Chambers Street.  where will they really end up?  Ground Zero?  TriBeCa restaurants and bars?  South Street Seaport?  It's a great opportunity for the neighborhood, but I'm also a little worried.  I guess what'll really happen is the crowd will distribute itself through TriBeCa, Chinatown, SoHo...  Probably the BPC restaurants will do well.
