I don't remember Kiddies Kingdom but do remember Coaster Corner vaguely. I have a habit of remembering weird details but remembering very little of substance. One of those was in the early 90's when most of the park was laid with the brick paving it still has throughout today. Before this, most of the pathways were laid to tarmac (some still are). I think Towers Street and Talbot Street were laid differently (as can be seen in the above 1986 picture), or maybe both just painted tarmac? But both were laid to the generic brick paving they have today around 1990-1992.
Anyway, point is, I'm pretty sure they also laid this brick paving in Coaster Corner around the same time. This leads me to believe that Coaster Corners closure could possibly have been a quick and hasty decision as they wouldn't have bothered to lay new paving in an area they were going to close shortly after?
Or perhaps I'm just going senile and someone who has worked there and been in that area since it's closure can confirm I'm just going crazy? I don't know why, I just have this lingering memory that it was originally tarmac and then laid to brick paving with the rest of the park shortly before it's closure?
