No worries, it's actually a simple route. I'm cheap and so will not be taking a taxi -- I'm going to opt for the subway instead, and hope you will follow suit using these directions (give yourself 45 minutes):
From the Hilton:
- Walk three blocks north along Avenue of the Americas/6th Ave to 57th Street station, about 5 mins
- Subway - F - Queens Blvd Express/ 6 Av Local (8 stops), about 15 minutes
- Arrive Second Avenue - Lower East Side - 2nd Ave
- Walk east along Houston, turn right on Allen, walk to Bluestockings at 172 Allen (about 5 minutes from subway station)
Truly hope to see you there.
