My family plan to visit Jiuzhaigou and Huanglong for 3 days this June. We will fly from Chengdu to Jiuhuang airport and arriving at 9.40AM. Upon arrival, is it better to visit Huanglong first and then stay overnight in Jiuzhaigou itself? Or should we go straight to Jiuzhaigou first and visit Huanglong later before returning back to Chengdu? I saw that Huanglong park is closer to the airport. Is there a car with driver that we can hire to bring us to Huang Long and then to Jiuzhaigou hotel that evening? Thank you
