Shouldn't we plan to come to Hong Kong from Huizhou and stay in Hong Kong, and then how to get to Disney from our hotel?

If you check online, you will find that there is a bus to Tsuen Wan, Hong Kong at the bus terminal. If you stay in Tsuen Wan, it will be more convenient to go to Disney, because Disney and Tsuen Wan are closer.

Take the West Rail at Tsuen Wan West Rail Station, get off at mei foo station, go to Lijing, then transfer to Tung Chung Line to Xinao, and then transfer to Disney Line.
