Saudi Prince Fahd al-Saud has spent some 15 million euros ($20 million) during a private visit to the Disneyland resort near Paris.
Prince Fahd al-Saud is said to have booked entire areas of the park over the 22-24 May period to celebrate getting his degree.
Euro Disney, which runs the theme park, confirmed that a prince had spent three days there with some 60 guests.
Disneyland says it regularly organizes private events for firms or people.
The festivities included tailor-made events involving “rare Disney characters”, Euro Disney told the AFP news agency.
Special security was put in place for the prince, one of the park’s top customers, added Euro Disney.
The theme park attracted 16 million visitors last year, but Euro Disney says it has not made any profits since it was set up in 1992.
Last year, it lost 120.9 million euros in the first half of its financial year compared with a net loss of 99.5 million euros in the same period a year earlier.
