Hi, how do I get to Subway Line 2 from Xian Xianyang Airport?

Well, there is no subway station at the airport nowadays. Thus where is your destination? Upon landing, you can take airport shuttle bus East Street Line and get off at Grand Metropark Hotel (East Street). The ticket fare is CNY 25 per person. And the trip takes around an hour. After arriving, take a taxi to Bell Tower Metro Station (Line 2).

We're staying at the Novotel SCPG at No 33 Wei Yang Road. There is 2 of us. Is it better just to take a taxi?
Thanks

Yes, you can take a taxi to the hotel directly. The fare may be around CNY 120. :)
