from jiuzhaigou to airport evening

Hello. I have a problem. I arrived today to jiuzhaigou, in pengfengcun community. The hotel personnel say me that there is no bus in evening to airport.
My fly is jul11 at 9:40. My plan was to go to jiuzhaigou park on Jul 9 and 10. At evening take a bus to sleep near to airport.

What can I do?

Thanks
