Would you please help me how can i get to Double Tree by Hilton Hotel Xiamen-Haicang from airport?

You are suggested to take Shuttle Bus – Haicang Line to Haicang Hospital first, and then take Bus 857/801 to Aluohai City Square. Then walk south for about 5 minutes to your hotel. It takes about 1 hour and CNY16.

By the way, the shuttle bus from 9:10 to 16:00 is with an interval of about 1 h, and the last one leaves at 17:30.
If you can’t catch it, you can take a taxi directly, which takes about 40 minutes , CNY50-60.
