Pleasure Beach have never actually given a reason to why it has been closed, and I doubt they'll give a reason if it closes again at the end of the month. It may be frustrating, but thats sadly the way PBB work, nobody knew at the time that The Whip, Turtle Chase, Vikingar and the Cableway were going to close, one day they closed and were eventually removed.
The odd thing is, while Bling was closed, Goldmine was open, but now Rollercoaster has re-opened, Goldmine has been closed again.
I really have no idea what the thinking is behind Rollercoaster and Goldmine, but I really hope they are both open through the summer months.
