In reply to Gwain:
Went last year. Expensive to get in, then not a lot of interest. Overall I found it boring apart from climbing the polystyrene "ice tower".
Things like the wine and beer tasting from various parts of the world are an expensive con - cheaper to go to the supermarket!
There was a lightweight tent which interested me, but they only had one - erected, so I wasn't able to judge it's packed size and weight.
I'd rather browse round a good outdoor shop for free.
