One more question hahaah, where can we stay in Huanglong and is there early morning buses to the Airport??
I think I've got most of the trip organized thanks to all of your comments and replies. It might help you in the Future... From Xi'an take a early morning flight to JiuHua Airport (Around 300 RMB in advanced, ride shuttle bus to Jiuzhaigou (45 RMB), spend the day and get used to the altitude, next day visit Jiuzhaigou park, spend the night there and next day morning take early morning bus from Jiuzhaigou park to Huanglong (40 RMB), ask to being drop off at the Huanglong scenic entrance, there is a place to leave your luggage there. Spend the night in Huanglong and next morning go streight to the Airport to flight back to Xi'an 9:45 AM (300 RMB).
Thanks!!! Nicest triping....!!
