Visited Thorpe yesterday. Not a lot to say that hasn't already been mentioned by others, but I have some thoughts on the day. Sorry if the post is kind of long.
Firstly, Derren browns ghost train... by far the worst experience of this attraction so far. We waited outside at 12 since there wasn't much else to do anyway. We were told that there was going to be a "slight delay" in opening, and a member of staff came and told us that even if the ride opened, we still had an 80 minute queue. We were opposite the banana ride, which is three trains at most, I think she was trying to get rid of the queue. After the "slight delay" (45 minutes is not a slight delay) and 15 minute queue, we got on the ride. Then, after the preshow, a member of staff stood in front of us and said "in the next room, there is a Victorian train carriage suspended by chains"... Doesn't that kind of ruin the surprise?
As others have said, the missing final scene and broken headsets leaves the ride feeling incomplete, and honestly, boring. Also, when did the volume in the headsets get turned up so loud?
He mazes were hit or miss. On one hand, Blair witch, platform 15, and living nightmare were fantastic, though Blair witch was too short. I really like how in platform 15, there is an actor who follows you round the entire maze, just far enough away that you keep looking over your shoulder.
Deadcreek woods and do or die fall are both decent mazes. Both are enjoyable, but have thier flaws. Do or die is by far an improvement on sanctum from last year.
Vulcan peak, though, is a disaster. There is absolutely no redeeming features, with the only positive(?) being that it's amazing how the I'm a celebrity building can double as a post apocalypse, lost for centuries building with no effort, though that's not really a good thing. The storyline is confusing at seems to change every few minutes, and the preshow doesn't help (and why did they have to use the seats, that was just really unnecessary and uncomfortable?). The finale of the maze achieved absolutely nothing, other than giving me a painful static shock.
As already mentioned by others, operations were appalling, meaning I only managed six of the seven mazes, and only two rides (DBGT and rocky express). This extended to the car park, with an actual fight taking place at the barriers because someone didn't want to pay £15.
TL;DR: it says a lot that I enjoyed my day at Chessington more
