An absolute must-see when in NYC. The all access ticket starts with a very well-done guided tour of the site and grounds of the memorial, and includes admission into the museum and the observatory tower. Our tour guide, Brian, did an outstanding job incorporating personal memories and local connections that were really meaningful and made for such a special tribute. Couldnāt ask for a better experience. (Tip: the first 90 minutes are all outdoors so dress warmly and be prepared for changing temperatures.)
