Large Group Tour in Hong Kong

Have you booked a transfer back to HKIA? If yes, the best ones are the Standard Octopus Cards, with which you can ride on MTR, Light Rail, trams, ferries, buses, taxis, and go shopping. It is very convenient.

Otherwise, you can consider Airport Travel Pass with one single journey. You can ride on AE train back to HKIA. Moreover, you can ride on all MTR lines (except Airport Express, East Rail Line First Class, Lo Wu and Lok Ma Chau stations) within 72 hours after swiping it at the entrance gate for the first time. You can also top it up, and use it as a normal octopus card on 4th and 5th day. The AE ride is valid for 14 days, so no worry about it.
