There are a few bits that I think desperately need re-tracking, the drainage needs looking at as it was a swimming pool/queue line when I visited on a rainy day and the outside of the station needs an overhaul!
If it was a wish-list I would have the plaza built at the bottom end of the site, more smoke and light effects and I would black out the tunnel completely.
is the plaza idea not possible now they changed the plans relatively last minute to build the staffordshire knot lower down - where as before the ride would have been higher up (or just that element which meant it could have stalled easier!?) with the plaza under the staffordshire knot.
the ride just needs general TLC as some of the themeing definitely feels rushed, for example if you look at the concrete area surrounding the staffordshire knot, and how untidy it looks around the edges at the top by the fencing etc.
It's obvious at least some work will be done - definitely the draining issue, but how far will merlin go? ideally they should keep to their advert and make the indoor section a bit more interesting (although i'd be more than happy if they made it pitch black, and constantly filled it with mist, as i love the strobe light, it's so disorientating!). would they realistically do any retracking to remove the jolts?
but wouldn't keep our hopes up too much for any extra visual changes apart from the general TLC which is required considering it was rushed to open and left a bit unfinished in places - and guessing that would be their priority)
