My teenaged son and I took this tour during a recent day trip to NYC. I’ve been wanting to take a tour of the hidden secrets of GCT since the terminal was restored in the 90s. Gabby was our guide and she was very knowledgeable and did a terrific job telling us the history and using photographs to keep her tall engaging. We loved seeing the whispering gallery, the hidden tennis court and learning more about this wonderful building. I would highly recommend!
