Very well worth the price to get the guided tour, memorial/museum, and observation tower package. Brian Cudina did an excellent job leading our group, providing interesting information about the day of 9/11, clean-up, Oculus, the memorial, and the new One World Trade Center tower. He really made the event vivid for all of us -- adults who remember it happening, young adults who were children at the time, and children who were not even born then. His retelling of incredible first-hand accounts, including his personal experience and how his family was impacted, make this a most valuable experience. I absolutely recommend this package.
