I want to stay 4 days in HK which card is best for me.

If you will use Airport Express and MTR a lot, the Travel Pass is suggested. If going to mainly use other public transportation like bus, MTR and ferry, the Standard Card is recommended, and your kid can get 50% off (Child Card).

Hi,
Thanks for reply.
As mentioned I have to got hotel from Airport and return. I have to travel tourist places like Disney land, Ocean park, etc in Wed, Thu, Fri and Sat days.
Should I buy Travel pass and Octopus standard card. I do not know whether I have to depends bus,MTR
If I buy travel pass, can I travel in bus and MTR
if I buy standard card can I travel Airport Express
Which is the best way to save money

You are advised to buy Standard Octopus Cards, which can be used to ride on Airport Express, MTR, buses, ferries, trams, taxis, etc. Each adult pays CNY 50 as the refundable deposit and CNY 100 as the stored value; each child aged 3 to 11 pays CNY 50 as the refundable deposit and CNY 20 as the stored value. It is very economical and convenient for you!

By the way, Airport Express Travel Pass is applicable on MTR for three consecutive days, but not on city buses.
