You can also get a Citibike membership (which I'm pretty sure is still under $200 for a year- it's gone up recently though so don't quote me on that!). PATH to 33rd, hop on a Citibike for those last 10 blocks. Citibike membership is good in JC and NYC so you can ride it any time you choose at home too.

Personally I take my personal bike to the ferry, but I work in SoHo so it's a quick ride vs. midtown.
