Twinlakes Theme Park wants permission to hold live music events and outdoor cinema screenings for hundreds of people.
An application for a variation of the premises licence at the park, which is on the outskirts of Melton, will be considered by the borough council on Tuesday morning.
B B & B Leisure Parks, the owners, also want approval to sell alcohol and hot food after 11pm as part of their licence variation.
Twinlakes has had a licence since 2015 to serve alcohol between 10am and 6pm.
Members of the council’s licensing sub-committee will decide whether the application is successful.
