Our favorite part of the tour was the 911 memorial, the first responder wall, the meaning of the Occulus building and the surviving tree from 911. Jenn Andres, from Experience First was very knowledgeable and informative. She was so wonderful and we loved her enthusiasm and her kindness. Overall, this was the best experience we had while visiting NYC. I would reccomend this tour experience to family and friends and Jenn was AMAZING!
