what bus stops the closest to the cable car at Badaling?

I AM CONFUSED - i READ THIS INFORMATION ABOUT THE 2 DIFFERENT 919 BUSES. IS IT TRUE THAT THE NON AIRCONDITIONED BUS STOPS CLOSER TO THE CABLE CAR?
WE NEED TO STOP AS CLOSE AS POSSIBLE TO THE CABLE CAR FOR MY ELDERLY FATHER TO WALK.
PLEASE ADVISE
Tickets for bus No.919 with air conditioning is CNY12 /person. And it will take you less than one hour to reach there, but it still takes about 25 minutes to walk to the ticket office of the scenic spots area.
Tickets for bus No.919 without air conditioning is CNY8 /person and it will take more than one hour to the great wall, but from the terminal it is only ten minutes walk to the ticket office of scenic spots area.
