Can not recommend Chessington, resulted in nothing...

Can not recommend Chessington, resulted in nothing but disappointment and tears for my children. Huge queues for rides with fast track pass holders streaming on to every ride Infront of the lower class standard ticket holder. Many rides we queued for broke down and shut before we got to the front. Meaning we wandered back and forth across the park from queue to queue. Eventually we purchased some fast track tickets for Scorpion express, which we were not able to use due to the ride breaking down and opening and closing before totally closing. Staff couldn't use a measuring tape to save there life telling me my son is 1.1m, he is 1.22m with out shoes on at home, when I questioned staff were extremely defensive and dismissive. This meant my son couldnt go on the tiger rock ride he had been talking about going on for weeks. Honestly we do want our money back for our park entry as it's supposed to be a fun day out but the kids did not get any enjoyment from it.
