Shaolin Temple entrance fee can use for how many days?

I plan to stay in a hostel within the temple, which I read from website that to enter the hostel, I need to pay the temple entrance fee. I would like to use the option from Longmen Grottoes to temple bus at 14:30, which include the entrance fee. Do I buy this bus ticket at Longmen Grottoes ticketing office? What are the chances this bus seat will run out? I will be visiting in mid of Sep 2019. And I actually wanted to visit temple the next day, which I wondered if I need to pay for the entrance fee another time. Where does the bus stop at Shaolin Temple? Is it at the entrance or another distance of walk. We'll be carrying our luggage
