Taking the bus from Hong Kong Airport to Century Novotel on Jaeffe Road in Wan Chai

I will be arriving at 11:10 pm into Hong Kong so may be able to get to the bus terminal around 11:45 pm at night. What is the fastest way by bus to the Century Novotel, how long by bus and what is the fare?

Also, what if my flight is delayed and I arrive at the bus terminal after 12 am then what bus should I take?
