Two weeks- although I find (as another with a couple of AD kids LOL) that staying out gets easier as the transition-stress wears off.
I'd camp for longer happily but Dh is self employed so whilst can manage things from a laptop for a fortnight (we do one week in the middle of nohere sans laptop at Whit) he does actually have to post the stuff he sells at some stage so two weeks is a maximum.
I never do one night; have in the past and it's beyond pointless unless for something special.
This year we have a week, a 2 nighter, a 4 nighter and I cannot remember if I booked ten days or a week for the main one
