Hiking day from Jinshanling to Simatai. Accommodation and fee questions

Hi!
I want to arrive next to Jinshanling part of the wall in the evening and stay in hostel or with my tent for 1 night and in the morning go to the Great Wall.
Is there any place like this and how much can it cost?
Also,if I'm walking from Jinshanling to Simatai do I need only 1ticket for whole trip or new one for each part of the wall?
