A grass strip with a pub nearby sounds ideal but 20 people or so descending on a country pub at Sunday lunchtime may not have the desired outcome. If you try and book it before hand the conversation goes something like this
'Hi I'd like to book a few tables a couple of months in advance'
'Certainly sir, for how many people?'
'Err, depends how many turn up on the day in fact if the weathers grim or the strip is waterlogged we probably won't turn up at all'
'Certainly sir, please send a non refundable deposit of £200.'
