A SAUDI prince has spent 15 million euros ($A20.41 million) for three days of fun at Disneyland near Paris to celebrate his degree, the group that runs the theme park says.

Prince Fahd al-Saud booked entire areas of the park between May 22 and 24 for his 60-odd guests. The festivities included tailor-made events involving "rare Disney characters", Euro Disney said.

Special security was put in place for the prince, one of the park's top customers, it added.

The theme park attracted 16 million visitors last year but Euro Disney has not made any profits since it was set up 20 years ago. In the six months to March, the group had a net loss of 89.1 million euros compared with a loss of 11.8 million euros in the same period last year.
