In 2003, Allan Zeman, known for leading the creation of the popular Lan Kwai Fong entertainment district of Hong Kong, was appointed Chairman of Ocean Park Corporation, a position he held for 11 years.[6]
In 2005, the year that rival Hong Kong Disneyland opened, Ocean Park unveiled a Master Redevelopment Plan (MRP), under which older features at the park were rejuvenated and new areas developed. The number of attractions more than doubled, from 35 to over 80. The Lowland was redeveloped as a new area called the Waterfront, while the old 'Headland' became 'The Summit', with polar and rainforest exhibits. A dedicated thrill ride area, Thrill Mountain, opened, and the children's area was refurbished as Whisker's Harbour.
