It's simply a completely unnecessary waste of capital expenditure, on equipment that will frequently sit idle either being bypassed or broken, or consume disproportionate staff time that would be much better spent elsewhere.
Sorry but it is not. The centres are a visitor attraction and customer experience is very important. Having to queue to get a ticket when the vast majority of people have extremely positive experiences of handsfree ticketing systems is a bad customer experience. Suggesting a bad customer experience is a good thing is beyond stupid.
Also apparently staff to sell tickets come free; news alert paying less than minimum wage is illegal.
It is the same stupid mentality that says we need lots of drag lifts rather than chairs because they provide up lift in conditions only the mental go out in, Which is another bad customer experience. Though I would note that there is a change in this direction but like the UK COVID response it's "too little, too late".
I note you have quietly dropped the guff about using a handsfree left pass you where spouting earlier when it was pointed out to be the guff it was.
The special weather of Scotland is just an pathetic excuse. They make stuff work in the middle of the North Sea for crying out loud. There is nothing special about the weather and it is not beyond the engineering capabilities to man to make systems work in the weather conditions.
This season we most certainly do not want people trying to purchase tickets in the carpark, the point about advance sales is so that numbers are limited by people not travelling without a ticket - to stop base facilities being overwhelmed and also because the ski areas don't want people to spend money on wasted trips, they want people to spend their money on trips where the lift company actually gets some £££ at the end of the journey.
True, but it would be easy enough to make the system require purchases 24 hours earlier. I also suspect that the proposed system will not reach a wide enough audience and people will turn up regardless unfortunately.
