I think they are a complete waste of time, go on a scare maze or rip around on a coaster in the dark? I know which I would choose. My girlfriend went a couple at Thorpe last week, I think it was Asylum and Saw Maze? Oh well, lets just say she and the girls she went in with were unimpressed by them.
I would not worry too much about it now as you wont be able to venture into one now for 11 months as they are all now closed. Unless you fancy the Saw Maze at Thorpe?
