We arrived in NYC a day late due to a canceled flight and thought we would miss the tour we had scheduled, but Sheldon rescheduled it with no problem whatsoever. Sheldon was very helpful as far as scheduling the tour and tailoring it to exactly what we wanted. He also stayed in touch with us to make sure everything was going OK. He was very nice and easy to talk to. We did the four-hour tour and it was amazing. Our tour guide was Chris and he was so knowledgeable about the whole city, extremely nice, and funny. We went to Central Park, Fifth Ave, 9/11 Memorial, City Hall, The Village, and more! He answered every question that we had, let us know where to eat, where to shop, and how to get around for the rest of our trip. It was our first time there, so Chris was a huge help. And if I felt like we needed help throughout our trip, even after the tour, I would not have hesitated to call either Chris or Sheldon, so that was very comforting. I will also add that the driver, Victor, was very professional and extremely nice as well. The tour was amazing! I would recommend this to anyone and also tell you to not go to NYC without this tour!!
