We caught the bus from Stroudsburg, PA, near where we were staying. Peter took care of all tickets, including the subway.
We were able to modify the tour route to see what we wanted, as it was a small group. Peter has a lot of knowledge, having grown up in NYC, and he added a lot of color to the trip. We covered about 10 miles of walking and got to see all the highlights we asked for: 9-11 memorial, Times Square, Brooklyn Bridge, NYC Library, and much, much more.
The highlight was a trip up the just-opened Summit viewing area at 1 Vanderbilt. The view was spectacular, and we caught it at sunset. Worth every penny!
