It might be just Looping Group clearing space for some new attractions more befitting of the park’s present target audience. Looping invest reasonably well in the properties they own, and they received substantial Middle Eastern backing quite recently, so I don’t think it’s out of the question that they might want to invest in some new family attractions that the park’s present target audience might enjoy more.
When one door closes, another opens. I fully understand why people might be skeptical, but just because Drayton are becoming more family-focused, it doesn’t necessarily mean that they’re on their way to closure.
