Merlin Entertainments has reduced the price of its standard annual pass by 25% during the month of May.
The price of the cards has been reduced to £119 from the normal price of £159, however the premium annual pass is not discounted in the sale.
Merlin sold approximately 70,000 annual passes during its January sale, which is typically the time at which the greatest discounts are available.
The standard annual pass this year has additional restrictions, preventing access to the Merlin-operated attractions in London on UK bank holidays.
