Mickey Mouse should be really worried about people like Shum Nai-ho.

The middle-aged man from southern China could have ridden Space Mountain or posed for photos with Donald Duck at the new Hong Kong Disneyland, which was expected to be a top attraction for mainland Chinese.

Instead, Shum took his wife and daughter to Hong Kong Ocean Park, a 29-year-old marine-themed park many thought would be wiped out by the time Disneyland celebrates its first anniversary this Tuesday.

Just the opposite has happened. In the past year, Ocean Park has experienced its largest attendance boom ever, luring customers with its cheaper ticket prices and diverse attractions like dolphin shows and a cable car ride with stunning views of the South China Sea.
