One day, 3pm to 10pm. Some bloody festival. What happens at 10? Do the exhibitors have to stop serving?
Using a name like that is asking for trouble. It builds up expectations which, if (should that be “when”?) they are not met, will lead to a lot of bad feeling.
Has this been advertised elsewhere? Any newspaper or radio exposure?
They are obviously too small and have not publicized it well enough, to use that name.
Look at the website, no details and the event is little over a Month away. They should have had a website up months ago, with details of the location, a list of some of the beers, accommodation and travel tips, links to exhibitor's websites, etc.
I love the idea and we need more of this sort of thing, but Great Irish Beer Festival? They need some perspective.
