Recovered enough to comment now....
That was an excellent event. The location is perfect (able to bring family in campervan and intersperse beer drinking with swimming etc), the bar is great (their bar food was excellent for those who wanted a change from the barbeque). Most of all though, the event was good. I've been to many festivals, on both sides of the counter, and there is usually a beer or two that should not be there... This time though, I tasted every beer (hic...) and while I didn't like them all, they were all of high quality - well done to all the brewers involved.
If anybody is communicating with the organisers, the only change I would suggest for future events is to have half pint glasses. I overheard many people (mainly, but not exclusively, female) complaining about holding pint glasses. The breweries also inevitably ended up pouring more than half pints into the glasses for 1 token, but I doubt they were overly concerned about that.
