We had a wonderful time in this observation place. Of course, the 9/11 memorial at night is incredibly moving, and climbing to the top of this tower was a unique experience. The projections in the elevator and especially the projection on arrival with the discovery of the pink view of the sunset ... sublime! Bravo for this imagination and this quality! We visited the 3 emblematic towers of the city and we found The One Tower to be the most complete visit.
