It was a similar story last night, Vortex, Samurai, IAC and (obviously) Tidal closed all day, then at one point Swarm, Colossus, Saw and Slammer were all shut, plus Rumba, Rocky and Loggers as it was after 5pm giving a total of 11 rides/attractions simultaneously closed.
Obviously Thorpe has had a reputation for poor reliability/ride availability for the best part of 10 years but even by their low standards the start of Fright Nights has been appalling for downtime.
