If the Hampshire one is anything to go by you will need a venue with a lot
of parking, some refreshments available, and most importantly, toilets. That
one started small and has snowballed, gets quite manic at times so choose a
venue that will allow you to grow, you don't want to have to move after a
couple of years. And don't forget the advertising, always key.

Thank you, I'll take a look through.

Nick has mentioned that the lack of parking may be an issue. Our local
church hall has toilets and refreshment area, with a fairly decent sized
hall, but there is no side room where kids could be kept entertained,
unfortunately. Plus being a church hall, it would only be available for the
Saturday, not the Sunday.

But we shall see!
