How to get to Sheraton Fuzhou (near Straits International Conference) from the airport?

It would be a little complicated by bus. First, take the airport express to Plum Garden International Hotel. Then walk about 150 meters to Yuanxicun bus stop to take the bus No.129. And get off at Aofeng Park where transfer to the bus No.136 and finally get off at the Sheraton Hotel. The duration is about 1.5 hours and the fare is about CNY50 - 55 per person. Taking a taxi takes about 40 minutes and CNY120 or so.

Thanks for your prompt reply! Would transportation be easier if I were to stay at Westin FZ instead?

Well, there are more than one Westin Hotel in the city. Which one do you refer to?
