How Can I get from Baiyun airport to China Town Hotel Marriott by Bus or subway?

I wonder whether you refer to the China Hotel by Marriott? If so, both subway and airport express bus would help.

For the former way, you can take line 3 to Jiahewanggang and transfer to line 2 and get off at Yuexiu Park. Leave from exit D2 or E and you can see your hotel. It costs CNY7 and takes around 40min. For the latter way, you can take express bus line 5 and get off at Dongfang Hotel. Walk southwards along North Jiefang Road for 2-3min to find your hotel. The bus fare is CNY18-20.
