I love them but haven't been able to go for years due to my depression causing me problems in crowds.
Chessington used to be great when the had the zoo parts in it because it combined 2 of my favourite things - zoos and theme parks.
When I was a kid growing up in Broadstairs Dreamland/Bembom Brothers was only a couple of miles away in Margate. Was nowhere near the same scale as the likes of Chessington etc but had the Mary Rose, The Looping Star and the Victorian Railway. The latter was pretty cool, was the oldest amusement ride (roller coaster probably isn't an accurate name for it but it was pretty fast) in Europe I think.
Had a bit of a dodgy experience on the Mary Rose though lol. It was the shape of a ship that started off rocking and then eventually turned 360 degrees a few times. Before it started the safety thingies came down and secured you in but for some reason mine came down and then came loose as the bloody thing started lol. Luckily it had some steel bars going across the top which I clung onto for dear life lol. My mate's face was a picture of horror when I flapped the safety thingy up and down as we were spinning around lololol
It ended up burning down in the end which was a great shame, some sort of insurance scam I think because it hadn't been open for years.
