Not too late. We are filling up now but can always squeeze a few more in right up until last minute. We can always pop out to get extra supplies if needed. Space for tents isn't an issue as my neighbour has said we can use his lawn if needed. Luckily we now have excellent neighbours and that makes life so much easier.
Only limiting factor is speed of catering as we are simply a private house not a pub/restaurant. Our chef has now been banned from partaking of any further alcohol after last night
so he should be sober enough to cook about 40 breakfasts each day. It is not "fast food", it is quality food so may take some time but will definitely be worth waiting for.
