During the Second World War the Admiralty, who had already taken over his camp at Filey, asked Billy Butlin to construct two new camps; one in North Wales and the other in Scotland.
Butlin found 85 acres (34 ha) on the coast neighbouring the Heads of Ayr and opened a camp in 1940.

Butlin took back ownership of the camp from the Admiralty after the war, and in 1947 Butlins Ayr was opened to the public after some reconstruction work.

Heads of Ayr holiday camp contained all of the tried and tested Butlins ingredients: the famous Butlins Redcoats, a funfair, early morning wake up, a dining hall (with the cheers going up when a waitress dropped a plate), indoor and outdoor swimming pools, a ballroom, a boating lake, tennis courts, a sports field (for the three legged and egg & spoon races and the donkey derby), table tennis and snooker tables, an amusement arcade, a medical centre, a theatre, arcades of shops, a chairlift system and a miniature railway.

In 1987 a £25 million investment programme was announced.
Work began in 1988 with £12 million used to construct a new swimming pool and upgrade the accommodation.
A further £13 million investment followed over the next five years.
Once the renovations were completed the camp was renamed Wonderwest World.
