Hi, i want go to shenzhen from airport hongkong what transportation can i use?

Well, Coach Services of Hong Kong Airport are available at the Mainland Coach Station of Terminal 2. There you can take a coach to Shenzhen directly. I'm not sure why not go to Disneyland from the airport first cause it is more convenient than from Shenzhen.

From the airport to Disneyland: You can take the airport express and get off at Tsing Yi. Then you can transfer to Tung chung Line and get off at Suuny Bay where you can catch Disneyland Resort Line.

If you only want go there from Shenzhen, the route is as follows:
East Rail Line - West Rail Line - Tung Chung Line - Disneyland Resort Line.
The whole journey takes almost 2.5-3 h.
