Our Great Wall trip was fantastic. Myself and partner were the only two guests on the tour, so we had a private guide, private driver and private car (sedan) rather than a bus. We arrived very early at the Wall, and were the only people there! Imagine having the Great Wall of China to yourselves with not a soul in sight. The traditonal foot massage afterward was a fantastic experience - much better than what I've heard of people being suckered into Jade shops or other add-ons. Best ever of almost a dozen Viator tours. Highly, highly recommended.
