I'm not so sure about a new coaster, I think Icon more represents a realisation that it's been a long time for a park with Pleasure Beach's stature not to open a large new coaster, I don't see it as the start of a chain of new ones (like Steeplechase > Revolution > Space Invader > Avalanche > Big One) - but we'll see!
It has been a long time since we saw major investment in terms of thrilling coasters, but this isn't the first time we have seen long period''s between investment. Look at between 1958-1977. That included recovery after the war, but given the tragic events of 2004 I can fully understand why the brakes were put on somewhat.
When LT took control we saw coasters installed in 1933, 1934, 1935 and a complete renovation and new layout in 1936. When GT took over we saw Steeplechase (77) Revolution and Water Chute (79) Tokaydo Express (80) Space Invader (84) and Avalanche (88)
While I don't expect anything as significant as the examples above, I do think this will be the start of something special IF Icon proves to be a success.
My worry is Icon is fighting against the parks diabolical entry system and hours of business. I ride of that standard deserves more than the queues it is getting. I am not buying the throughput theory, 2 trains on Icon is only 2 seats more than the Big One on 1, so on 3 trains its the equivalent of the Big One being on a train and a half.
Now when the Big One crashed it was forced to reopen on 1 train. The queues hit 2 hours and often 3 hours, don't forget that's on one train, which is almost what Icon has when on 2.
Where BPB do seem to be winning is with customer feedback, I have never seen so much positive feedback about the place. I still believe though that BPB really need to conduct some market research among those who are on the prom, not in the park to find out why they aren't going in.
A £5 entry fee for none riders would be a lot easier to digest if it were given back in ride tickets or food/drinks, alongside a significant reduction in the number of tickets needed per ride. I'm sure with a few simple changes BPB could be a lot busier, taking a lot more money while maintaining the entry fee they want.
