Justin Wan was a fabulous host! Husband and I traveled with 3 boys (15,13,9). We did trip 2AA, the Gubeiku section we found very beautiful/peaceful and did not see any other tourist, however the kids enjoyed the Mitianyu section because of the toboggan ride. Vivian at Great Wall Adventure efficiently responded to all our emails and the trip was exactly how she had portrayed it, we were able to trust her. It was our first time to China and it was a great family experience.
