Hi! Were planning to go to hongkong on oct 29. We've booked a hotel along nathan road.

Well, you can take airport shuttle bus no. A21 to Nathan Road Station.
From the Nathan Road to Disneyland, take Tsuen Wan Line at Yau Ma Tei Station, Exit C, and get off at Lai King Station. Transfer to Tung Chung Line to Sunny Bay Station. Then take Disneyland Resort Line, and get off at Disneyland Resort Station, Exit A. The ticket fare is 19 HKD per adult.

if you're travelling with 3 others and 3 LUGGAGE (MAX) you might be better off taking a cab to nathan road. it's faster and probably costs just a little more than the bus fare individually. in going to disneyland, study the MTR color coded lines or ask the hotel on how to get there. saves you money.
