Hi,I have some questions for my visit at Jiuzhaigou. My plan is to take a morning flight from Chengdu to Jiuzhaigou, and take bus from Jiuzhaigou to Chengdu.

1. May I know where to take bus from Jiuzhaigou to Chengdu? How about the schedule and fees?
2. I am planning a 3D4N trip to visit Jiuzhaigou, Huanglong and Ruo Er Gai greenlands. I will be taking morning flight and reaching Jiuzhaigou at 0825. May I know how should I plan for the trip?
Day 1: Ruo er Gai (since not too far from the airport)
Day 2: Jiuzhaigou
Day 3: Huanglong (If possible, I will take a night bus back to Chengdu)
Day 4: Take afternoon bus back to chengdu.

Awaiting your reply , thank you very much!
