This was a very memorable trip. The shuttle arrived exactly on time at the hotel. Everything was well coordinated. Our tour guide (Jenny) was excellent, and talked about many interesting facts related to the historical sights. She was also very considerate in accommodating our dietary requirements. Only thing negative I found was food quantity :(. Otherwise it was great experience. The vehicle quality was good, guide had good command on English and with friendly behavior. Also both the sites (Great Wall and Summer Palace are worth visiting especially for nature lovers).
