I did a tour with Donna on May 24. I travelled with 4 students. Donna was exceptional and funny and she knows a lot about Xi'an, the terracotta army and the surroundings. What really impressed us was the schedule. Everything was punctual. This started by the meet and greet with our driver on Friday evening the 23th. Than Donna picked us up at the hotel next morning for a crazy day, cycling over the ancient wall of Xi'an, a tour in one of the buildings, visiting a local market nearby, the Terracotta Army, the palace of the first emperor and the show Legends of the camel bells. It was almost overwhelming but Donna and her driver made sure it all felt relaxed. There was enough water provided (it was hot in May!) and time for lunch. We can recommend Donna anytime for an interesting tour. We experienced more 'China' in 1 day than 3 days in Shanghai. Thank you Donna, maybe meet again next year
