I wouldn’t say it’s ridiculous. It’s been advertised in plenty of places that masks will be required on rides; social media, emails, videos, posters as the park. There’s been plenty of notice.
In terms of guests getting to the station to be refused, they won’t be sent back along the queue line. They’d be either asked to leave via the exit or via a fire escape door as in the wicker man station.
Whilst I agree that it might be more practical to wear masks at all times, government guidelines don’t enforce this. And it’s not comfortable either. I’d say that Merlin/Towers are trying to strike a balance between guest satisfaction and staying safe.
I’m not saying people should have to wear them in the pathways while walking around, but I definitely think people should have to wear them in queuelines, particularly in indoor sections of the queueline. If a staff member enforced putting on masks at the beginning of the queue then that would make the process a lot smoother and make me feel more safe.
I’m guessing there aren’t staff members in queuelines to enforce social distancing then, it’s just down to trusting the guests?
