How to go from HK international airport to holiday Inn express causeway bay

Hi, you can take shuttle bus E11 or A11 to get off at Wan Chai Fire Station, Hennessy Road. Then your hotel will be within walking distance.

Is the e12 or a11 more than one hour and a half by bus ? Is there zcwuicker route via airport express than hotel shuttle that would stop within walking distance ?

Bus E11 takes about 75 minutes, but the A11 takes about 65 minutes.
The airport express is much quicker than taking a bus directly. From the airport, you can take the airport express to reach HK Station. There you can walk to reach Central Station. Then you can take the Island Line to reach Causeway Bay Station. From there, you can walk to reach your hotel in abou 3 to 5 minutes.
