We deliberately set out to have a much cheaper day today (and it worked!)
We used our (7 day) subway tickets to take us down town to the Stanton Island Ferry (free), took in the views (free), came back on the same ferry, grabbed a sandwich ($15.73) and then jumped back on the subway back to the hotel.
A quick rest then back on the subway to browse the shops at Union Square before walking to Washington Square Park. At the park we sat in the sunshine watching the street performers for a short time before walking to Greenwich Village. Another hour of walking around before buying takeaway pizza from Joe’s ($9) which we ate in out hotel room.
