I will be touching down at PVG at about 6am. What are the ways to go to Starr Hotel Shanghai?

You can take shuttle bus line 5 to local Main Railway Station. Then your hotel is around 1.4km away. You can walk north along Datong Road to find the hotel after 20min. Or take a taxi to arrive in 3min. By the way, the first bus of line 5 leaves at 06:30 (T1), 06:35 (T2).
