I can't wait to see this completed. I wonder where they will fit the family coaster in that mess.
Family coaster?
I assume you are referring to speculation/hope that there will another attraction in the area aimed at families/younger audience, in the same way Klugheim had Raik. If there is anything I think it is highly unlikely it will be a family coaster again.
To be honest the lack of rumours about, or signs on the construction site of, any other ride at this point is making me start to have doubts.
As is the rumour of a hotel; which would explain the still unanswered question of the meaning of the teaser: Rookburgh will be an area you can "experience by day & night" . Although I question the feasibility of constructing even a small hotel in time for Summer 2019.
Maybe somewhere at street level they could just enclose or integrate a small family/kid flat ride(s) in the area.
Or as they take up very little space maybe a kiddie coaster, similar in scale to the Kleine Zar in Hansa Park or Baaa Express in Europa? It's something they lack in their line up and it would well positioned beside the more kids/family orientated areas of Fantasy and Berlin. (Rookburgh +2?)
If there is no hotel, or something else (event or entertainment venue, restaurant, shops etc.) to explain the day & night teaser, located there; they could build a significant family attraction on the currently un-built section of the site bordering the road (seen in the foreground of the overview pictures). And the lack of rumours is because the park have just managed to keep it a complete secret this time.
There's too many variables to accurately predict anything at this point. But I do hope there will be something else.
Also off the back of the most recent pictures I've seen on a couple of forums and on social media some people questioning if Rookburgh will actually be done for 2019. To quell any concerns here's a
picture of Klugheim from 25th August 2015. Worth noting as well that Klugheim's wooden buildings and structures were put together by hand, while the concrete/brick buildings and steel structures (which as we have already seen are delivered to the site finished) can be done quicker. Unless major technical problems arise (although with the previous extensive testing on the prototype at Vlodrop, and the fact Vekoma aren't Intamin, I'm confident it will be fine) they should have no problem completing the project in time.
