Currently, the Vintage Cars has to be one of the most randomly themed rides, in the world. There's blue woodchip to represent the sea and yellow woodchip to represent the beach. So you drive around in a vintage car, at the beach, with a giant squid stuck to the bonnet.....
Anyway, I think this should be made into another quirky dark ride. It wouldn't take too much investment ot stick a building around it, and maybe theme it as a Haunted House stlye attraction? They could theme the exterior to resemble a ship, so there's like a Ghost Ship style theme going on!
The UK badly lacks decent dark rides, so to do this, and sort out the other two, Pleasurewood could become a little hub for dark ride lovers.
Very true, on the subject of the The Ponies. Have a look at George's Dinosaur Adventure at Paulton's Park; the use of grass mounds separting the track and the theming make the ride look really good. As they stand I think the Poinies look quite untidy and lazily themed.
