I've thought about this, then realised I knew how I felt all along. I do not see attractions as either being thrill, experience or whatever you want to call them, I see all attractions as an opportunity to entertain an audience, to manipulate their emotions and to engage them in a theme/ story.Sure, you get rides that are catered more towards thrillseekers, likewise, you get rides that are aimed more at smaller children, but the main aim is that it has to entertain a very large spectrum of guests as possible because you want them to come back again, recommend their visit to others and in the long run this means more profit and more investment.Greater interactivity is the way forward for all theme parks I feel. Disney have shown this in their recent queueline updates on attractions such as Winnie the Pooh and Haunted Mansion. Both attractions appeal to families yet the beauty is, you can take anyone through them and they will find something that they will be entertained by.I can understand why Merlin are so hesitant to invest in dark rides; to build a decent one you need a budget as big as a multi- million pound coaster, if not more so. With these rides, you do not have the advantage of having the queue interact with the ride and so in order to keep your guests entertained, more effort needs to be put into scenery here. Scenery and special effects are more expensive than what people realise: the Vampire Horseman for example, cost thousands and thousands of pounds just for that one scenic element.However, with the huge spectrum of people that dark rides cater for (due to their accessibility to families), I'd argue that this would make the huge investment worthwhile. I'd love to see dark rides start playing a starring role at our theme parks like they do in other countries, though sadly I feel as though Marketing struggle to find a way to market them and would not be able to guarantee a return on the investment like they would with a new coaster or area, for example.I've sort of gone off on a tangent here, as usual. My main point is supposed to be that you can have whatever type of transit system you want (coaster, water, trackless, tracked dark ride...) but they also need to have substance, story and a great deal of creative depth to them and I do not see them as separate types of attractions. What one person finds entertaining and thrilling, another person may find boring.
