I am not sure about other things but one thing that a visit to Disneyland teaches you is patience... Every ride, every show tests your patience with long wait that too in the humid Hongkong heat...I feel one day is not enough to explore the whole disneyland and that too with small kids or infants.Don't forget to take a map from the entrance and plan which section you will visit first before you enter.Another tip is to take rides while the public is busy checking out the parade....One thing must is to see the shows as that are more entertaining specially the Frozen show. Remember that it gets sold out very fast.Also don't forget to take umbrella, lots of water and sun protection lotion.
