Don't bother. It's no where near the memorial site. It's a small room full of photographs, most of which are in the official museum. It was all rather awkward and uncomfortable and amateurish to be frank.
We had a wonderful experience at the Ground Zero Museum. The young man running the tour was a pleasure and we enjoyed being able to appreciate and pray for all of our FDNY service men and women who did such an important job on that horrific day. We are humbled by their great losses and heroism.
I visited here in August 2016. We had visited the 9/11 Memorial and Museum and the 9/11 Tribute Centre but this was a completely different experience. The girl working the day we went was very welcoming and professional. We arrived about 15 minutes after the start time and didn't think we would be let in but she was very accommodating and even let us have extra time at the end so that we were able to see everything. I cannot praise her highly enough. I would definitely recommend this workshop.
