Hi, Can anyone give me some information on this bus service?

I read a trip report that talked about this service being one of the highlights of Hong Kong. I am interested in taking this bus to stanley market, but am worried that I wont know where to get off, and then back on again and I don't want to end up in the middle of no-where!!

Is this bus a loop? Do the drivers speak english, and would they be helpful to a woman travelling solo? Any information that would assist me in being confident of not getting lost would be appreciated

Thanks
Michelle
