arrive at jiuzhaiguo airport at 7 am. which attrcations place i should go first / b4 check in hotel

I suggest you go to Huanglong first. After visiting, u can rent a car or van back to JZG and check in. In the next day, go to JZG Scenic Area.

Hi, what's the best way to get to Huanglong? Where could I book a car that would take me to see Huanglong in the morning and then bring me to Intercontinental Hotel in the afternoon? How much does this cost typically?

Well, there are shuttle buses at the airport to Huanglong for your convenience. Besides, you can easily hire a taxi or a private car there to take you to Huanglong and they may charge around CNY200. Also by hiring a taxi or car, you can go to the hotel you mentioned.
