I have a theory on how the vehicle will move (I guess it can be classed as spoilers) Spoiler
So you board from Side A. The train leaves via Side B (opposite Side A)... but the tube train is suspended itself. Then at some point there is track underneath. It is on both for a while before becoming fully dependent on the bottom rails. Would cause a lovely jolt as well, perfect for a jump/bit of drama.
I'd expect the resort have a projected opening date for the behind the scenes team, however like Dan said I don't expect this will be publicly available until the day comes.
I personally think it'll be next weekend, but who knows at the end of the day!
I did think though that when they decide it's finished they'll say that the opening day is Thursday or something along those lines. They need to let the press know to attend surely. Otherwise it's a wasted free PR day.
A dedicated media event will probably be organised for a date after the attraction now opens rather than as a preview which was likely the plan previously.
They will most definitely be annoyed, however I'm glad they have decided to loose a chunk of income as opossed to opening a half finished ride. If the ride has technical issues that could ruin a riders perception of the ride then it's only fair they try to fix these, but seeing as preview are now going on I'd be inclined to say that the attraction is more or less ready to go, that being if it doesn't bump into anymore...complications.
While it's ridiculous how long they're taking with the opening and stopped communicating any kind of specific opening date, I am pleased they've learned from their mistakes and don't open up an attraction with half of the effects not working. I remember experiencing "I'm a celebrity" on its first opening week felt rather...poor. :P
It just seem like all the hype and communication has gone, I mean are we even certain its going to open next month, On the other hand I would rather have all the kinks ironed out now rather then later, I just hope it lives up to the price, Expections and the delay for it all.
Next thing you know it won't open at all this year and we will have news like...
BREAKING NEWS: Derren Browns's Ghost train delayed to 2019 :lol
But i am also glad that they are taking time with this ride, it should (hopefully) open soon (I can see this weekend being possible). Lets hope its all worth it....
