I attended this last year too, and it was excellent fun and value.
There was no queue to get in, they handed you your tokens in a little paper bag, and in you went.
The tasting sizes were generous, and most of the brewers were very keen to be available at their stands to discuss the beers.
Some of the larger beers were 2 tokens a sample (such as Boatrocker crazy massive IIPA they had last year) but with beers like Taco and Monster Mash for a token a pop... you can't go wrong!
