I will be staying in a hotel near the Chengdu Luomashi Station.

And need to get to Xinnanmen before 8 am in order to get on a bus headed to Jiuzhaigou Valley.

I also wish to know if I must go to Xinanmen station a couple days before or the previous day to buy bus tickets for the trip to Jiuzhaigou or if there are online alternatives that hostel officials can help me with.

Regards
