Hi, is it easy to go backpacking in Jiuzhaigou and huanglong in 2 days?

Hi, my friend and I plan to go to Jiuzhaigou and Huanglong in 2 days this month. We'll fly from Chengdu to Jiuzhaigou at night, and plan to stay there the next day, then head to Huanglong in Day 2 and fly bk to CD late evening of Day 2. Is there any bus from Huanglong to Airport? Do you think we'll have enough time to travel around like that by bus? Or we'd better rent a car? Thanks.
