Hasn't it been more or less established by now that it's going to be a while before Alton gets in to that valley in any significant sense?
We're waiting for a convenient fire in the valley, or some kind of mysterious disease which affects several species of trees and all of the locals
Next (bigish) coaster is likely to be Coaster Corner, or replacing the Flume. I reckon we'll be lucky to see more than one coaster before 2020.
There may be some room between Forbidden Valley and Gloomy Wood - bit it sits on the edge of the listed/protected area, so planning will be very tough to get over.
There's the chance on the car park by air though.
I think to be honest, it will just be re-themes, tarts ups and a few replacement flats for the next few years.
That's what I'd do
I'd certainly not change Duel back to the Haunted House, I wouldn't want to put anyone through that pile of drudgery again - it was so boring. There was a reason before the make-over that nobody rode on it, it was dull as dishwater and everyone was bored of it.
Sorry if it sullies people's fantastic memories of the ride, but it really wasn't
that great - the memory of the ride is greater than the ride itself was: beware nostalgia.
