I've got 100-120, all invited to the whole day. I think Babybellas is my wedding twin!
We're getting married in our parish church, then onto our village hall (which is free, as I painted it for them!). Got fish and chip van and ice cream van, then a friend that owns a pub is doing bacon baps and veggie burgers for £1per head in the evening! Alcohol is tricky, we're getting wine and cans from her wholesaler, but need to keep lager cool, so I'm thinking big bins with ice in.
I advertised locally for some staff to come help as it was going to be impossible to do it totally ourselves.
Having village fete outside, with looooooooads of games (friend with pub also does a country fair at their pub once a year, so we're getting the hook a duck etc) giant bouncy castle, face painting, wooden croquet, cricket, large tombola of tat and donated gifts, guess teddy name, air hockey, table football, giant jenga.....list goes on!! If only we can have good weather :(
My hen is the 8th. My friends have arranged it as a surprise so I have no idea, though I did state I did not want a 'night out' getting drunk in town in a sparkly Ann Summers cowboy hat 
aka hen night from hell haha. So all I know is that it's out of town, and involves drinking!
