Document 4: Camelot: Camelot is a castle and court associated with the legendary King Arthur. Absent in the early Arthurian material, Camelot first appeared in 12th-century French romances and, after the Lancelot-Grail cycle, eventually came to be described as the fantastic capital of Arthur's realm and a symbol of the Arthurian world. The stories locate it somewhere in Great Britain and sometimes associate it with real cities, though more usually its precise location is not revealed. Most scholars regard it as being entirely fictional, its geography being perfect for romance writers; Arthurian scholar Norris J. Lacy commented that "Camelot, located no where in particular, can be anywhere". Nevertheless, arguments about the location of the "real Camelot" have occurred since the 15th century and continue to rage today in popular works and for tourism purposes.

The Peppa Pig World theme park area is based on the children’s television series character. The Lost Kingdom theme park area includes 27 animatronic dinosaurs.

The park covers 140 acres of land and features a collection of around 80 species of birds and animals, in addition to the rides. Most of the theme park rides are designed for children, which is why the park considers itself a family theme park.

Document 8: Olympia Looping: Olympia Looping, also known as Munich Looping, is a portable steel roller coaster designed by Anton Schwarzkopf and built by BHS. It is the largest portable roller coaster in the world, and the only one with five inversions. It appears at many carnivals in Germany, most notably Oktoberfest, where it made its debut in 1989. It is named for its five vertical loops, which resemble the Olympic rings. Although they are clothoid-shaped, their shape is closer to circular than the ones on most other roller coasters, so they exert unusually high "g"-forces on the passengers (up to 5.2 g). The entire structure weighs 900 tons and requires a space 85 m wide by 36 m deep. The ride usually runs with five cars per train, though at events such as Oktoberfest and Winter Wonderland in Hyde Park, London, it runs with seven to increase throughput in busy periods.
Document 9: Giovanola: Giovanola Freres SA was one of the prominent thrill ride manufacturers in the world.

In 1998 Giovanola started marketing directly under the name Giovanola Amusement Rides Worldwide. The company was based in Monthey, Switzerland. During its last years in business, Giovanola fashioned steel behind the scenes for companies such as Intamin and Bolliger & Mabillard. The company also built its own thrill rides and roller coasters from 1998 to 2001. Examples of Giovanola roller coasters are Goliath at Six Flags Magic Mountain, Titan at Six Flags Over Texas and Anaconda at South Africa's Gold Reef City.
Document 10: Bayern Kurve: The Bayern Kurve is an amusement ride made in both a portable and park model that debuted in 1965 and was invented by German engineer Anton Schwarzkopf. During the ride, riders sit in one of the sixteen bobsled-themed cars that travel at a high-speed around a circular single-hilled track. Riders start in an upright position and as the cars pick up speed, they tilt inward toward the center of the ride. This ride is also known for its loud horn which is similar to that of a diesel train engine that blasts its loud roar when the ride reaches maximum speed. Also akin to a train, the seamed track creates the same rail "click-clack" railway sound, particularly at the lower section of track in the front. Additionally, the ride has a distinct whine that increases with speed due to its tire/blade drive.

Document 13: Corkscrew (Alton Towers): Corkscrew was a steel roller coaster manufactured by Dutch company Vekoma to a design by Arrow Dynamics. The coaster was located in the Ug Land area of Alton Towers in Staffordshire, England. It was the park's oldest ride and is considered the greatest factor in promoting the new theme park to the British public. It was one of the first double-inverting coasters in Europe (the first in the UK), so it received much publicity and avid popularity in the 1980s. Waiting times for the ride frequently reached 6–9 hours during the first few months of operation at Alton Towers, and the park would often be forced to close early as it found itself swamped with visitors long before the evening ever came.
