Please tell me the bus no/subway from kunming west bus station to Wei Long hotel? How much the fare?

No subway can take you for the journey. Bus or taxi can be good for you as it is around 6km between the two destinations. Well, walk from the Western Bus Station to Huangtupo Lijiaoqiao Xikou bus stop to take bus no. 116 and get off at Nanping Street Xikou Station. Then you can walk to the hotel within several minutes.
