hi! could you tell me how much it actually costs to take Bus A11 to Central (Jardin House stop) and how long it takes? Same with Bus A21 going to Cameron Road, TST? I looked on the Citybus site and got confused with the fares posted. Also, they got the head time (intervals?) but no estimated travel time. I am trying to figure out which would be best to take going to our hotel in Tsim Sha Tsui, and to be there on time to watch the Symphony of Lights. Thank you very much!
