when is the Pearl River night cruise start and for how long the cruise and do they serve dinner

Hi, many night cruises are scheduled. Which dock are you going to start? For example, if you start from Tianzi Dock (near Haizhu Square/Plaza), the cruises are scheduled from 18:40 to 20:55 every 10-20min. Generally, the whole cruise trip takes around an hour! Most of them serve tea and dim sum instead of dinner!
