Tough question, slappy, I'll have a crack at answering although it may be a bit of a ramble. :lol:
I think they need to join the park together in some manner. At the moment, it's too bitty.
There's a lovely area near t'Ultimate, Raptor Attack and the "castle" toilets. The wooded area near the pub/drop tower is also quite atmospheric. The swinging ship is also in gorgeous setting.
All of these areas are found on the outer extremes of the park. The rest of the park, the bulky bit in the middle (which should be the heart of the park) is a field with a few rides plonked down on a large slab of concrete. It's soulless.
Looking at a couple of other parks, the central area is essential. It acts as a crossroads in the park and sets the scene. Thorpe has Amity Cove, Flamingoland has the Seaside Adventure area, Chessington has Market Square and Drayton has the area around the arcades.
It's the same reason why I think Camelot doesn't work well. There's the brilliantly themed area, with a another bit of a park tacked on at the far end.
Going back to LWV, the extremities of the park are really nice, they should be left alone (perhaps smarten them up a bit). By creating a central hub with shops, arcades, food places, game stalls, benches, even a ruddy fountain, I feel it would join the park up. Maybe relocate the crazy golf near the go-karts, add in a massive adventure playground, a circus...just do something that could help tie it together. What about re-diverting the pathway that runs from the entrance plaza towards Twister towards the centre of the park?
Don't get me wrong, even though I recommended Drayton to herbinator over LWV, I do think LWV is taking very tiny steps in the right direction. Their marketing has kicked up a gear and the re-theme of Rat are examples of this. With limited cash resources, I wouldn't exactly know how to improve the park but by bringing it closer together yet maintaining each areas individuality, the park could unlock it's potential.
