There was a thread a few years ago about an amusement park somewhere in Asia or Europe, I think. There were lots of photos from someone who was visting it. I remember that there were very few people at the park that day...maybe some schoolchildren. I also remember that they had to get their tickets from a kiosk. Does anyone remember where the amusement park is?
Maybe if you post this on the UK board, they can describe some amusement parks there and perhaps it'll ring a bell for you. Good luck.
