We used Jenny’s service for the Great Wall.
We have a family of six including a toddler. We had More than enough room in the van. Jack was waiting for us in our lobby on time. In the van he provided us water and fresh fruit. Jacks english was great! He’s full of good information. He made my wife and I feel safe and comfortable, especially with four children. He guided us up to the Wall and took a few family pictures for us. Totally worth every Yuan! Highly recommended!!!
