I lived in Qingdao many years. I am HongKong people.
when you arrive Qingdao airport you can buy one at the lobby.
Fly from Shenzhen is cheap around 2100 roundtrip. Hong Kong ticket 2,500.
I don't think you would choose hotel nearby airport, because it is not much convenient
for you to go outside working. most of visitors would stay at downtown,
there are many hotels ranged from Rmb 300-700. deluxe 1200.
usually I would stay at Haitian Hotel very near airport about 30 mins drive.
taxis fare about Rm 50-70.
April of this year quite good temp.8c-15c. not humid
what are you going to do in Qingdao, what business ? because I have my company in Qingdao. may be it can help you about trade.
