Airport→Huanglong→Jiuzhaigou shuttle

If we are arriving the airport at 10am (in June), would there be enough time for us to take the Airport shuttle bus to visit the Huanglong Scenic Area in the later half of the day before proceeding to Jiuzhaigou? How long is needed approximately to visit the Huanglong Scenic Area?

Do we leave the luggage in the bus, visit the Huanglong Scenic Area, and then go back to the same bus to proceed to Juizhaigou, or we need to alight with the luggage and catch a later bus? What is the latest time or the last airport shuttle bus to leave Huanglong for Jiuzhaigou?

If the airport shuttle does not wait long enough or does not have a later bus, is it possible that we take a bus from airport to Huanglong, visit the Scenic Area, and then separately take one of those local buses to Juizhaigou?
