About kunming changshui international airport, I am familiar with it.

You don't have to check your luggage by car. You can take the airport bus to Yi Xi Hotel, and then take a taxi to the west. Or take the No.82 bus directly to the west, and ask at Yi Xi Hotel to know where to take the bus. Accommodation can be close to the Yi Xi Hotel, which is the city center. But there are more night buses to Weixi, aren't there? Can you drive there? There are also accommodations near the western passenger station, but the conditions near the station are poor and expensive.
