This may be odd but....I can't help wondering if anyone knows why the actors in the mazes are all wearing these gloves?? They don't seem to look like they'd be for warmth and so must be a health and safety thing but none of the actors had them on at Alton towers last year so thought I'd ask as it's bugging me ? we are off to fright nights in 10 days, can't wait!
