This is my second tour with Shai. After having an amazing initial tour I knew that I had to book a second. I learned so much from him. He was more proficient in his knowledge than any of my professors in college. He is friendly and easy to get along with. I felt like we were old friends. I will definitely book another tour with Shai. I am so glad that I did not try to experience this amazing place on my own. I would've barely been able to scratch the surface without him.
