It's essentially a fairground.
One of the coasters is a vibrating bottom coaster, another is a travelling inverted coasters and there are a few more coasters I think, one of them is OK. There are also several spin & spews.
It's a small park, you won't need long there if it's quiet.
I did a video for the 2008 Live, it's pretty crappy by today's standards, but it may give you an idea.

If you're going with mates, then it should be a half-decent day out, but it's not a park that I'll be rushing back to.
