We did a lot of tours while we were in NYC for the week, and this one was the best out of all of them... and the reason for this was Ibeth. She was knowledgeable, enthusiastic, and energetic, and she imbued this upon us. Despite it being quite cold that day, the energy that Ibeth exuded warmed us all up haha. Yes this was a somber tour of a sad event, but the way Ibeth presented it kept us engaged in a way that we won't forget.
Bonus: She also showed us the Oculus and the huge underground transportation hub and mall, and she got is to the 911 museum on time, and gave us precise directions to the One World Observatory for after that. I strongly recommend doing this tour with Ibeth!
