Where to Stay in Miyun or Luanping

I am traveling from Beijing to Jinshanling for overnight and enjoy the wall for the whole day. I have 2 options:

Option 1: Beijing - Miyun by 980 Express
-Sleep in Miyun (where can I sleep? I can not find any place in the internet)
-Next Day take a bus to Jinshanling (Where and which is the bus I have to take? I cant fint it)

Option 2: Beijing to Luanping
- Sleep in Luanping (where can I sleep? I can not find any place in the internet)
-Next Day take a bus to Jinshanling (Where and which is the bus I have to take? I cant fint it)


Which one do you suggest me?
Thanks
