The pass was announced at the same time as reports claimed attendance in the park’s second year might not reach four million, falling below government and company expectations and the 5.2 million visitors recorded in the park’s first year.

The park’s vice president for sales and travel trade marketing, Josh D’Amaro, would not, however, confirm the reports and also denied the latest strategy was designed purely to boost attendance.

D’Amaro said: “The annual pass we introduced about a year ago is extremely successful, with 85,000 passes sold to date, so the logical next step is to refine that programme to new segments and to the next level.

“Adding the student offer was sensible from pricing and flexibility perspectives.”
