Parker, who was also formerly the chief executive of Whitbread and also holds the chair at Darty, will take over from Resorts founder David Vaughan, who is retiring due to ill health.
“I look forward to meeting the staff, caravan owners and holiday customers, and playing my part in adding value to this successful business,” Parker said.
Park Resorts, which is owned by private equity group Electra Partners, is Britain’s largest holiday parks operator with 48 properties across the country.
Electra chief investment partner Alex Fortescue said of Parker: “His credentials in the leisure sector are second to none having transformed FTSE 100 listed Whitbread. His knowledge and experience of the leisure sector will be invaluable to Park Resorts as it continues its growth.”
Parker is also a non-executive director at Burger King.
