We had booked the two day trip with demi, from India. It was worth all the way which included airport pickup to drop back to airport. We covered two days with demi which included Tianmen square, forbidden city and Temple of heaven on day 1 and summer palace, Great wall at mutianyo on day 2. Demi is knowledgeable with decent English and does use travel time to give a lot of historical background of the visiting places. She very well maintains the time and makes appropriate suggestions for food based on our preferences. I would definitely recommend Demi, for those who are planning a Beijing trip with a friendly and well organized guide.
