I would imagine the bulky work will be done once the Winter events end so, from 4th January the ride can be themed accordingly. They will have 6 weeks before the Half Term event.
Unless there is snow, floods, storms...
I would say that this could just be a repaint but as the Spinball signs are in turquoise it's unlikely they would keep them with the new paintjob.
Sonic + Spinning coaster = interesting match (although I think the spining direction would make more sense on a ball coaster).
I still think the Spinball theme was unique just not implemented brilliantly.
Didn't that guy (nj... somthing like that) mention that the carts were broken. could there be some truth in what he said?
