Butlin's Filey: Filey Holiday Camp was a Butlins holiday camp near Filey, North Yorkshire, England, built for Billy Butlin's holiday organisation.  Construction of the camp began in 1939.  From 1939 to 1945 the camp was used as a military training base, as RAF Hunmanby Moor.

National Motor Museum, Birdwood: The National Motor Museum, Australia, is an automobile museum in the Adelaide Hills in the township of Birdwood, South Australia.

Butlins Bognor Regis: Butlins Bognor Regis is a holiday camp in the seaside resort of Bognor Regis, West Sussex, England.  It lies 55.5 mi south southwest of London.  Butlin's presence in the town began in 1932 with the opening of an amusement park; their operation soon expanded to take in a zoo as well.  In 1960, Billy Butlin opened his first post-war mainland holiday camp, moving both the amusement park and zoo into the new camp.  The camp survived a series of cuts in the early 1980s, attracting further investment and again in the late 1990s when it was retained as one of only three camps still bearing the Butlin name.  The camp has since seen a raft of new construction as the company moves from chalet towards hotel-based accommodation.

Butlins: Butlins (also Butlin's) is a chain of large holiday camps in the United Kingdom.  Butlins was founded by Billy Butlin to provide affordable holidays for ordinary British families.

National Motor Museum Monorail: The Beaulieu Monorail is a monorail linking the National Motor Museum to the Beaulieu Palace House.

The cars were originally of a streamliner design, but were modified to allow for more passenger space.  It was the first monorail in England.

Hard Rock Hell: Hard Rock Hell is a three day music festival currently held at Hafan y Môr Holiday Park, Pwllheli, Gwynedd, North Wales, and up until 2011 at Pontin's Holiday Village, Prestatyn, Wales.  Holding the festival in a holiday camp gives the organisers pre-built venues and stages and because of the on-site accommodation allows them to hold a multi day festival over winter/spring months when outdoor camping is not desirable.  The first edition of the festival was held at Butlins Holiday Camp, Minehead, England but the festival relocated to its current location in 2008.  The next edition of the festival will be held in November 2014.
