When I was at Towers in the summer I got talking to one of the ride hosts in the Galactica queue at the merge point for a while as the ride went down temporarily due to a loose article that was being retrieved. She mentioned that Bianca said Galactica was getting similar treatment to TCAAM/Nemesis over the closed season the theming being updated and the area being refreshed (I cannot remember for the life of me if she mentioned any changes to the ride hardwear as it was a while ago now). I know that things like this shouldn't be taken as 100% factual information, but the ride host definitly seemed to know what they were talking about - I remember her saying that Wickerman should be open by the end of the week, and I think it opened on the Sunday of that week - so they definitly were somewhat knowledgable about the behind the scenes info at the park.
