I’ve also been visiting since the mid-nineties. I suspect it was Cobra that put them on a lot of enthusiast radars, but the history is pretty much the rise and rise of Paultons Park. There’s the sentimental part of me that misses Percy the Owl and was sorry to see Toad Hall go, but looking at things objectively the investment and visitor numbers have pretty much gone in one direction.
Unless they add a GCI or a Mack Launch or something then Paulton's is still an absolute ball ache to get to if you live anywhere north of Milton Keynes. This park would be so much more successful if it was closer to London.
