My trip to Jiuzhaigou is planned on 25 Oct 2009. hopes to cover JZG and Huanglong in 1 and a half day. After that will proceed to Songpan and stay over a night. I intend to do 1 way flight and 1 way bus. Any advise to do Songpan or jiuzhaigou first if i arrive by flight? Total 4 days to explore JZG and Songpan, sound possible? If i choose to return from Songpan by bus, can i purchase my bus ticket in Jiuzhaigou? Would it be difficult to check into a hostel around evening time? – With thanks.
