Is there a direct shuttle bus to kelinhaotai hotel or motel from the xiaoshan airport?

Oh, you must refer to the GreenTree Inn, right? Well, there are many branches of it in town. If you happen to mean the one on Middle Zhongshan Road, I know the way:
take shuttle bus Pinghai Road Line to the terminal station - Pinghai Road. Then walk for around 15min or take a taxi for several minutes to get there directly.
