Our group had Chinese only and English only speakers and David's ability to convey the Chinese garden and Tiger Hill's historical context and artistic designs in English and Chinese captivated us for the whole day. We also had a very enjoyable boat ride and tour in Tongli. We were impressed by the varied content of the 1 day tour that David curated. We were in a bit of a pickle when the usual lunch place closed for the day to celebrate their 25th anniversary, but David quickly came up with another spot that served Suzhou style noodles with seasonal vegetables and other delicacies. Also worth noting was David had an comfortable and eco friendly EV. My husband was very impressed with the drive and park assist features :) He was also patient with my 3-year-old son.
