You have only got to visit places like Efterlin, Disney and park Asterix to realise how great and emersing that theming can be. As for the new fencing and signs, at the moment they do stick out like a sore thumb as they are new. Give it a few years and we will not even notice that they are there. The new fencing in the Katanga Canyon is not too bad, the only disappointing is the fact they have blocked the view over the bridge where you used to be able to watch the train came out of the tunnel next to the rapids. As for the quality of the recent new fencing around the park, well I took a good look around at some of the existing fencing and even though the new fencing is not the best fences in the park, these are also not the worst. Personally, if they did a proper job in the first place with regards to the theming and the cosmetic site of things , I think Alton can be one of the best theme parks in the word.
