And now a voice of a staff member (although I'm glad my areas rides were helpful )
Basically there are four rides at Chessington that you need to be able to get on and off without the aid of helpers at Chessington. They are the Runaway Train, Rattlesnake, Bubbleworks and Dragon Falls. Now I'm not exactly sure what the rule is about stopping Bubbleworks to allow guests in wheelchairs onto the ride (Peter may be able to explain further) What you have to remember is that the staff don't want to run the risk of getting in trouble for breaking a health and safety rule. It would be rude for me to ask how well you can walk but remember when you e-mail Chessington, is that the staff members were just going by the Code of Safe Working practise. They shouldn't have been rude to you though, and that is not on.If you have any questions about some of the disabled policies Chessington has just send me a PM, Ill try and help you out and maybe pass on your comments.
