Casper was an amazing tour guide! She not only was very knowledgeable, but was also extremely kind-hearted. She made an effort to make sure my mother, who was recovering from a knee injury, was well taken care of. We had a different tour guide for our last day in Beijing, and I can tell you the difference between the other tour guide and Casper was night and day. I would definitely choose Casper for any future travel. My family loved our time with her.
