Heres an idea if i could choose what to do with the ride. It would be called Alton Manor. I would replace it and go with a dark ride shooting game simalar to duel but with a twist... You do the classic haunted house shooting ride and then you reach what looks like the end station. The car keeps moving and your restraint dont come up. You the here a booming voice saying something along the lines of"Why leave the manor so soon? (evil laughter)". Then there is a small launch and your car then goes through the door at the end of the station you then go into a small dark roller coaster section with flashing lights and classic but large scale haunted house props. You then reach a brake run themed as a corridor and the voice says "I hope you enjoyed you stay at alton manor. Do visit us again soon."
You then reach the real station where you disembark.
This could be the rides backstory;
When futher work was being done on restoring the towers they unearthed a few paintings that had been made by the earls wife depicting the gardens and the towers. In one of the painting was an old manor situated south of the gardens. Merlin entertainments became increasingly interested in finding the manor and opening it to the public as part of the alton towers resort experience. They eventually found the manor in a clearing and it is now open to the public. Since being open, there have been stange sightings in the manor. Do you dare step inside?
I know i have written alto but once i started my idea i couldn't stop developing it.
