Haikou airport to Sanya Railway to Jinjiang inn

Hi,

1. From Haikou Airport I understand that I can take a train from Meilan Railway Station to SYRailway Station. Is Meilan Station inside the airport or I have to take a shuttle bus from the airport to Meilan station?

2. to Jinjiang Inn International shopping centre. Is bus 54 the right bus to take?

Btw, is it easy to commute by bus? What is the condition of the bus? Is it very crowded? I read that it is best not to take taxi.

Thank you
