Anybody got a feel how it might be affecting the school parties in terms of numbers? That's my biggest worry about crowds when I'm there in a couple of weeks.
As for when is Smiler going to re-open - it won't be dependent upon the HSE investigation needing to be completed. That could take a year (or even longer sometimes - I was involved in a big one which took 18 months). But that won't stop the ride re-opening as long as all evidence has been collected (which by now I'm sure it must have), and also any necessary improvements have been made to the ride.
Interestingly, I haven't seen any mention of any improvement notices being issued by the HSE yet. Normally a Prohibition Notice gets issued pretty quickly, before full facts are known. Then further improvement notices get issued, which are more specific with detailed requirements of what needs to be improved.
I'm surprised we haven't heard about any further notices being issued. One explanation could be that Merlin have already made the necessary improvements - a notice can only be issued if a breach of regulations still exists, and if Merlin have already done the work, further notices may not get issued. If that is the case, then there may be no reason at all for the ride not to be opened straight away.
But my own gut feeling is that Smiler will stay shut for the rest of the season - re-opening on its own is likely to attract more media attention. Furthermore, whilst people are still in hospital, re-opening may appear insensitive. I certainly don't think it will re-open until everybody has left hospital at a minimum. But I personally think re-opening at the start of next year, with the rest of the park, will get a lot less media attention, and that is what I reckon will happen.
However, as pointed out in a previous post, notorious rides often see a spike in visitors when they re-open - so more PR might actually suit Merlin (even though they wouldn't say so - what is the old saying - no such thing as bad PR?).
