Dp the boys and I went here last night and it was great It isn't cheap but seen as it's winter and we went after 5pm the prices are lower. I think they need to do something to draw people in though because there must've been no more than 10 people in. There were nearly as many lifeguards as punters.
I spectated last night but will go in next time and brave the slides
Apparently it's packed in the summer. I think it's a great place to go in winter as it's so warm, I was sweating buckets!
