The 3-day unlimited metro ride is tied with the Airport Express Travel. A single AE travel with 3-day unlimited metro rides will cost HK$250/person, while the double AE travel with 3-day unlimited metro rides will charge HK$350/person.
If you will not go through the airport, you may take the Adult Tourist Day Pass into consideration, which includes unlimited metro and light rail rides within 1 day. It costs HK$65/ticket. Notably, it is not available on Airport Express, MTR Buses, East Rail Line First Class, Lo Wu and Lok Ma Chau stations.
You can get these passes at the custom service center of every metro station, except Lo Wu, Lok Ma Chau and Racecourse Stations.
