I think they are a bit stuck with what to do really. It's hardly the best area in the first place, the whole area is just full of caravans and arcades and cheap shops. The market is clearly where they must make their money as its massive. So they could go down a few routes. Do a pleasure beach and charge an entrance fee. However I don't think that would work for them, purely because of the amount of people who must walk through for the markets and to look around. Or they can keep as they are, or just try and smarten the place up. However its hard for them to really smarten it up, purely for the type of people who will always go and visit because of the area and markets.
The place does need a good clean and paint, when I went earlier this year some of the rides (particularly the log flume) was so tatty and old, our boat was covered in duck tape!
