Ms.Cuison,

a)Disneyland to CityGate Mall: take Disneyland Resort Line back to Sunny Bay and then exchange Tung Chung Line and get off at Exit C of Tung Chung MTR Station. You will see the CityGate.

b)Disneyland to BP International: take Disneyland Resort Line to Sunny Bay and exchange Tung Chung Line to Lai King. Then take Tsuen Wan Line and get off at Jordan and get out at Exit C1. Walk along the Nathan Road and then turn right to go on Austin Road. Then you will find BP International.

c)BP to Ocean Park: Go to Jordan MTR Station to take Tsuen Wan Line to Admiralty. Then get out at Exit B and turn left to take No. 629 bus to Ocean Park. To go to the Victoria Peak, you need take No. 629 bus back to Admiralty and then take Island Line to Central. Then get out at J2 Exit and turn right and walk along Chater Road for a second. Then pass through Garden Road to reach Peak Tram Terminus to take a ride on the peak tram to get to Victoria Peak.

d)BP International to Airport: You can take airport shuttle bus from BP International to the airport. The charge is HK$110 per person per trip including 2 pieces of luggage. You can check these pages: http://www.bpih.com.hk/en/page/location.html

It takes about 35 minutes from BP International to the airport.

If you use MTR, you may take Tsuen Wan Line to Lai King and then exchange Tung Chung Line to Tung Chung Station. Then go to Tung Chung Bus Station to take S1 airport shuttle to the airport. In all, you need to spend around 1 hour on your way to the airport.

What's more, it is cheaper to use MTR and S1 airport bus than to take airport shuttle bus directly from BP International. The MTR and S1 ticket fares are less than HK$20.

e)If you stay in Hong Kong for a long time, you’d better buy an octopus card. You can get discount when you use public bus or MTR. To know more about octopus card, please see this page: https://www.travelchinaguide.com/cityguides/hongkong/transportation/octopus-card.htm
