่่่Jiuzhaigou ticket booking reseavation

dear sir or madam,
My name is Thirapat (Net) a backpacker from Thailand, I am wondering if I book Jiuzhaigou ticket from you and pay for the fee by credit card, then where could I pick up the tickets sir, and If I have these ticket I can enter the national park as soon as the opening time of the day imediately , right?
I have never been to China, but I would love to start now, from Chengdu Airport to Jiuzhaigou national park, If it doesn't bother you too much please give me some advice, I might land at Chengdu airport around 2 am on July 27 if it possible if i hop on the bus from Xinanmen Coach Station to Jiuzhaigou that morning?, and I will start the Jiuzhaigou trip on July 28 - 30 and do the HongLong journey on July 31 .... do I have to come back to Jiuzhaigou to get back to Chengdu on the next day (Aug1)? or I can stay at HongLong and spend the night of July 31 and next morning I can take bus back to Chengdu from HoangLong, straight away sir,
please give me some advice
I am Looking forward to hearing from you soon
