I think the reason they made the queue like it is was apparently creative; I heard somewhere that they wanted to highlight the contrast between the sadness of the queue and the happiness of the ride or something like that.
In terms of Smiler’s queue; I like the unique perspectives of the ride, but I’ll admit I’m not a huge fan of it on the whole. Maybe waiting in it for over 2 hours last July didn’t help, but I’ve become less of a fan over time, for sure. I don’t know whether it’s all the concrete and steel, but it seems very hot down there (at least it did in the summer of last year, anyway), and it’s somewhat claustrophobic with all the cages. I know they have to be there for safety reasons, in fairness, but I’m not a huge lover of the big maze of steel that the queue is, on the whole. I find it very confusing to navigate; you don’t really know where you’re going, or how far you are away from getting on, and I often get confused as to which way I’m turning next. With a queue like Wicker Man’s, for example, I prefer it because you do get a sense of progressing towards the ride, and despite the fact that the fences are still quite high in places, it feels a bit more open.
In fairness, Smiler’s queue design may have been intentional in order to add to the disorientation of the ride, so I should probably applaud them for the subtle little creative touch, but I’m not personally a huge fan, I’ll admit.
The indoor queue is perfectly fine, and I quite like the station and exit corridor, to be fair. The only bit I don’t really like about the indoor queue is the strobe that goes off intermittently; it makes me wince every time!
On the whole, it’s probably not fair of me to criticise Smiler’s queue, as I don’t think the park was really aiming for a Wicker Man-style theming extravaganza, but I’ll admit that it’s not my favourite queue on park. On the whole, though, I think Smiler’s theming is perfectly good for what it is, and I particularly like features such as The Marmaliser; that really is a dominant centre point!
