Do we think that Thorpe maybe scared to step of the toes of it's family orientated neighbours? Merlin potentially robbing it's own parks as visitors?
From what I can tell, it was all but confirmed that this was why they pursued thrills so aggressively in the first place.
Before Tussauds came along in 1998, Thorpe Park was very much a mild-mannered family park aimed almost primarily at young families. Under the ownership of RMC (not the RMC you’re probably thinking of, unfortunately), the park directly competed with Chessington and Legoland, and it never really went especially thrilling (the most thrilling thing RMC built was probably Loggers Leap, although X:\NWO was also aiming to be a more thrilling ride).
Believe it or not, Chessington was actually considered the most thrilling of the 3 at the time, as well as the most popular, and this meant that Tussauds were majorly painted into a corner when Kingston Borough Council wouldn’t let them build anything else major after Vampire. This meant that Chessington was consigned to being more of a family park, against Tussauds’ initial hopes. Tussauds initially satisfied their urge for a market-leading thrill park by building and developing Alton Towers, the pre-existing market leader in Britain, but they still yearned for one in the South.
Chessington’s move to primarily targeting families meant that Thorpe was in close competition with Chessington at the time, and also had fairly lax planning restrictions, so as such, Tussauds decided to buy Thorpe and convert it into a thrill haven in order to eliminate their closest competition in the family market (as John Wardley once put it, Tussauds’ mentality was one of “if you can’t beat them, join them”).
In order to not have the two Southern parks compete with one another, Thorpe was rather aggressively re-targeted towards thrill seekers with the surge of investment in the 2000s. While I’m unsure if the change would have happened quite as quickly or as jarringly had things like the Wicked Witches Haunt fire not happened, I think this path would inevitably have been followed due to the issue of the parks competing with themselves in the South.
When I write it like that, it really does put into perspective just how insane the 2000s must have been at Thorpe… I’d wager that few, if any, UK parks ever changed quite that drastically in a decade.
