Our booking was handled very well through Viator. The limo turned up on time, and the driver was very courteous. Unfortunately the tour guide was ill and it was apparently too late to organise another guide, so she soldiered through the tour, but after throwing up consistantly through the tour, she had to call it a day and leave. Although I do feel sorry for her illness, I do feel very shortchanged for our "3 hour" tour as she did leave the tour earlier than the 3 hours, and again although she valiantly tried to do her best, I feel if she was in good health it would have been so much better.
Both the driver and the tour guide were great. we enjoyed ourselves and learned about New York.
We had two, because the first time we had a dreadful limo (leaked inside!!) and driver (sped past the things we hope to see!). Annie the guide was great. Second time, we had Isaac and his Cadillac- much better. Really good at tailoring the tour to your interests. Highly recommend:)
