A Disney theme park in Hong Kong would attract an estimated 6.1 million visitors, significantly boosting the economy, according to a DBS Securities report. DBS said that 2.2 million local people would visit the park annually, along with 2.9 overseas visitors. Another million visitors would travel to Hong Kong specifically to see the theme park. The report said rumours suggested due diligence was being undertaken by the US-based entertainment company on the site of the closed Whitehead Detention centre. 'If the incremental tourists stay three nights in hotels and the other visitors stay an extra half day, then 12,200 additional rooms per night would be filled,' DBS said. Despite boosting the economy, hotel occupancy rates would not necessarily increase, as thousands of three-star hotel rooms would be built should Disney come. The report said the crucial variable that could alter the demand-supply balance was mainland visitors. 'Should three million additional tourists arrive per annum, instead of one million, they would fill an extra 28,657 additional rooms, creating a hotel bonanza,' the report said. Of the key developers in Hong Kong, Sun Hung Kai Properties and Henderson Land are believed to have the largest land holdings in the Ma On Shan area, and would benefit from the creation of a Disney theme park. 'If the park goes ahead, this will boost property values in the neighbourhood, especially those with similar completion dates of the theme park, estimated at 2003 or beyond,' the report said. Other benefactors would include air carrier Cathay Pacific, mainly through its stake in Dragonair. DBS said that a Hong Kong Disneyland could be opened after five years and a construction cost of $5 billion, plus land premium.
