There’s no real scientific way of measuring this, but from what I’ve heard (and I can only repeat my own experiences), the non-enthusiast members of the public I know who’ve visited BPB describe it as old, tatty and full of “rubbish old wooden coasters”
This is, of course, not an opinion I share. However, a few modern coasters, mixed with the classics would benefit the park’s reputation.
I know that people say that Icon hasn’t been a success and, if we base that entirely on short term marketing quick return on investment, then you could say it wasn’t a success in that respect.
But in terms of long term benefit to the park, Icon I think has healed to keep the park relevant.
But, who knows, that’s just a guess. How much of a long term benefit Icon has made to the park vs how the park would have performed without it, I guess, is something we’ll never know.
