How do I get to summer palace from Beijing jingyuan courtyard hotel in dongcheng?

Walk from the hotel to Dengshikou and take subway line 5 to Huixinxijie Nankou. Then get on line 10 and change to line 4 at Haidian Huangzhuang. Get off at Beigongmen and walk to the Summer Palace. It takes around an hour and CNY5 per person. If going by taxi, the fare is CNY60 or so, and a taxi can hold at most 4 adults.
