Ocean Park may raise admission prices by more than 50 per cent after completing its $5.5 billion revamp of the 28-year-old attraction. 'We will probably have to raise the price of our tickets after our redevelopment plan. If you look around the world, most theme parks set their ticket prices at 75 to 80 per cent of Disney's ticket prices,' the chairman of the Ocean Park Corporation, Allan Zeman, told a Legco panel meeting on economic services. Adult tickets for Ocean Park cost $185. Hong Kong Disneyland is to charge $350 when the Penny's Bay theme park opens in September. Based on the figures given by Mr Zeman, adult tickets to Ocean Park will rise to between $263 and $280, an increase of between 42 and 51 per cent. Mr Zeman said the park would continue to provide special offers such as annual passes for local residents and free admission to the theme park for children aged under three and people who are over 65. The redevelopment of Ocean Park is scheduled to finish in 2010. It is estimated that more than 5 million tourists a year will visit the park when it reopens after renovation.
