Early morning arrival at Kunming airport to Kunming train station

Hi,

Based on your reply on previous post,you mentioned that we could take the shuttle bus at Line 2 for early morning arrival at the airport (mine is around 2am ish).My questions are :

1.Which exit to wait for the Line 2 bus at the arrival hall?
2.Is the shuttle bus last stop is at Kunming train station ?
3.Will the bus stop in front of Kunming Train Station or somewhere nearby (any landmark)? Im planning to book a hotel nearby the station, so hopefully its not too far from the train station.

Thank you for your help!
