I have booked to stay at Green Leaves Inn on Sat 15th Sept.

We will arrive late afternoon and want to look around Gubei village and then catch the cable cars up to see the great wall at night. Can I pre-book the great wall at night? I am worried if we don't pre-book then the tickets might go, we are only coming to see it at night! Also do I have to buy entrance tickets to the park if I am staying? And if yes do I have to buy separate tickets for each day? We leave Gubei on Sunday 16th of Sept. Thank you for your help!

Kind regards,
Hayley
