It follows four previous Party in the Park evening concerts this summer, Flamingo Land Resort has just announced the details of their fifth and final 2017 concert on 2nd September.
“Party in the Park is a great way to spend a summer’s evening and guests can buy a theme park ticket for the day which then gives them free access to the concert" said Sarah Mills, Director of Marketing at Flamingo Land Resort.
"Alternatively they can arrive at 5pm for an hour in the theme park followed by the concert for just £10 each."
There is a wide variety of food and drink outlets around Riverside One so that guests can make it a social occasion.
The event concludes at around 10.30pm.
Flamingo Land, named as one of the UK's top paid-for attractions, is in Kirby Misperton, in North Yorkshire - just a short drive between Scarborough and York.
It's handy for repeat visits from all over the region, or for days out to and from the coast.
