I want to take the 16:00 bus from Chadianzi Bus Station to Jiuzhaigou County

Hi, my mother and I are traveling over the National Holiday between the 1 and 7th of October 2015. I don't want to waste two whole days on a ten hour bus ride, so I would like to take the 16:00 bus to Jiuzhaigou County. Will I be ped off close to a hotel and/or park entrance? How long does this bus take? I'm assuming I'll arrive in the middle of the night..will I be able to check in to a hotel at this time?

Also, if I was able to rent a car and driver for the trip, would they be able to go over night so I don't waste a day?

Thanks!
