Which shuttle bus I can take to go to Blue Horizon Hotel - Huangdao from Qingdao Airport ?

Take shuttle bus line 705 to the terminus: Huangdao District Government. The fare is CNY40. The trip takes about 105 minutes. Then, take a taxi to the hotel for about CNY 10.

Line 705 which you told above is the line Huangdao Special Line : Airport - Blue Horizon Marina Gold Hotel => It means i will take the shuttle bus to go from TAO Airport to Blue Horizon Marina Gold Hotel, then I will take a taxi to go Blue Horizon Hotel-Huangdao , is it correct ?
