Is that easy to find a taxi from the hangzhou international airport to JW marriott? Thanks!

Yes, in the airport you can have easy access to the taxi service. By the way, from the airport to the hotel, the taxi fare is about CNY100.

Actually, you have an economical mode. You can take the airport shuttle bus Wulinmen Line to the final Station. The fare is CNY20, and then walk about 700 yards, you will find your hotel.
