Unfortunately very disappointed:( we went there as tourists- from abroad. We had a disabled person over 60 in our group. We purchased a relevant ticket at the gate as well as a carer ticket. No one informed us that we could get a wrist band to fully "enjoy" disabled person's "privileges". So when we were trying to skip the queue and use disabled gate, we were told that we were not allowed. I would like to emphasise that my mum has obvious and visible disability and is using walking stick at all times. We were sent back to customer service desk to apply for a wrist band. I went alone (due to massive queue there) and was told that I couldn't get one on behalf of someone else although I had a disabled ticket in my hand. When I asked whether someone could go with me to deliver the wrist band to save my mum walking / I was told they were short of staff. I understand that someone can disagree with my point of view and say it's their disabled people policy and I was supposed to follow it. But I believe we should have been informed about all those rules when purchasing the ticket for a disabled person at the gate. And honestly we've been to London many times (including New Year's Eve fireworks) & love the city and its high standards when it comes to treating people with any sorts of disabilities. No one ever required any paperwork apart of a blue badge when you park your car in a disabled space which we obviously fully accept. The paperwork maybe make sense when people use the attraction many times over months. For us it was just one visit and I believe that staff could show some good will - especially that we talk about elder, visibly disabled person. I'm sorry comparing to all the places we've visited through years in London, Chessington is a disgrace for me.
