Which route should I take to go to Hong Kong Disneyland from Hyatt Regency Shatin by MTR?

You can take East Rail Line from University Station to Kowloon Tong Station and Kwun Tong Line to Prince Edward Station. Then transfer to Tsuen Wan Line to Lai King Station and Tung Chung Line to Sunny Bay Station. After arriving, take Disneyland Resort Line to Disneyland Resort Station, Exit A.
The whole way takes around 60 mins with the ticket fare of around 30 HKD per person.

Thanks a lot David.
