Wow. I hope Icon pays off for them as the situation seems to be pretty dire, and they do not have a global company like Merlin behind them to provide financial support if a loss is being made.
This may well be the case, but that's no good to those who are visiting in this quiet period. And to be honest, if I was planning a trip and saw of these planned closures I wouldn't bother going. If you are going to open your big new coaster part way through the season then try and give people a reason to visit before as well as after it opens, rather than just give up on the period before it opens!
