Our tour was led by Ray and he provided informative, relevant and honest facts. His personal recollections added meaning and perspective to the tour. He was both captivating and respectful, giving a true view into what people on the ground experienced on 9/11/01. The walking tour was insightful, the museum experience top notch and the One World Observatory provided expansive, beautiful views of the city and beyond. Overall, I feel there is value in the walking tour with a great guide because it prepares you for the full museum experience.
