Does anybody know a bus line from Foshan/Shunde ferry port to Nanhai Aloft Hotel?

No direct bus is available, as I know. You can take Bus 907 and transfer to Bus 351 at Tianfa Huayuan. Then get off at Gongyequ Avenue.
After that, take City Bus Sanshui- Shunde Express Line to Xiaotanghu Jingwan. Finally, walk east for about 5 minutes, you will see your hotel.

Dear Leila,

Thank you for you answer, it came to me a little too late. My address is on Gmail and I found your answer only in Frankfurt Airport.
For you, and may be for other people interested in that topic, I will tell you how did I proceeded.
I came from Hong Kong to Shunde by ferry.
After customs formalities for China mainland entry, I found a banner with the information that ferry travelers have at their disposal free shuttle to different directions.
For FS City I found one with the final stop at Crowne Plaza Hotel in FS. I had no time to check the other destinations, anyway the writings were only in Chinese and nobody there speaks other languages.
From that point I took a taxi to my hotel ( Aloft Nanhai - 70 RMB ) but there are also some buses to that part of FS. I remember that two years ago when I wanted to visit an ancient temple in a far district of FS starting from the same hotel I found a bus which number began with K and that bus had a stop in Crowne Hotel area.
Thank you again,
Dinu
