We're going to Beijing for 2-3 days, kindly advise:

1. From the airport, how can we go to Sofitel Wanda ? If we take airport bus line 3 where should we take off at Yabou Lu or railway station ? and how much taxi fare from that place (Yabou Lu or railway station) to the hotel.
2. Since we have only short time, we plan to visit Temple of Heaven on the 1st day (arrive Beijing airport 13.05 pm), and Gugong + Badaling Great Wall on the 2nd day, and the Summer Palace on the last day (our flight depart at 17.00 pm) Will it enough time for all ?

Thank you for your advices.
