Went there today.
I think it is a rip off. children go in free but you end up paying the tokens as the previous mum said turned out expensive (£10 for 3).
Besides the big pool there are no activities for children under 3(oh yes, a tiny bouncy castle) - I ended up lying and said my daughter was 3 and half so she could do the big slide (which she mastered very well)...
We had a great time because we were a nice group of people and my daughter had the chance to bond with her god father and at this age a few slides run and an ice cream are always a winner
I think if they want to do it next year, they have to make better value for money...
