Hi, I'll be arriving in Guangzhou airport at 12 midnight on 05 Dec 2013. Any taxis to ye Xiu? And how much?

Yes, the taxi will be still available then. Don't worry! Generally, the cab fare shall be CNY90 or a little more. Besides, airpoer shuttle bus will still be in service upon your landing. By that, you can get off at its termimus at CAAC Ticket Office, near GZ Railway Station at Yuexiu District. Then considering the distance to your destination, take a cab or walk to the destination.
