Visitors can access the London Dungeon, Edinburgh Dungeon and York Dungeon attractions this Saturday (6 May) for a one-off special entry fee: trading in their copy of Spare, the memoir by Prince Harry.
As the UK gears up for the coronation on King Charles III, the first 75 people at each location who hand over Spare at the ticket office will get in for free. After coronation day, the books will be distributed to charity shops.
