Europa was still a great park and much better (in terms of value for money) even before Blue Fire opened, and Merlin have made many more mistakes on big projects than taking a risk on just one coaster, so I dont really buy that. All successes come with taking risk anyway, and Europa have an excellent track record of taking those risks and making successes.
But I totally agree Europa has built their success over a long period of time. I think theyre a real beacon of the value in developing your park long term and making a success of it at every step. While Merlin are a clear example of how parks can be squandered by constant short term time and cost decisions.
I'm really pleased with the news although it certainly doesnt automatically mean any big change or improvement.
