I'm really keen to get the family out camping, my sister and all my friends going on about how great it is for the children has finally convinced me! DH is sceptical however- main things are children not sleeping (DS2 is 2yrs 3months and only just sleeping through most nights) and his sleeping comfort; plus he doesn't like the mentality of a lot of campers and caravanners (we spent nearly 3 months going round Oz in a campervan and the older caravanners were a touch annoying).
So, what could hopefully persuade him is more comfortable sleeping facilities and a decent campsite. DS1 and I slept in the garden the other night and he slept until 8 (normally he's up at 6.30ish), so that argument is hopefully sorted. 
We have 5cm thick self inflating mats- what would help make those more comfortable without too much stuff in the car? I find them ok but DH is 6ft2 and 17st so not many beds are comfortable for him.
In terms of campsites- we'd want a campsite that would allow campfires (fun) and not too manicured, but still have nice hot showers, good toilets, possibly electrical facilities to charge phones etc, maybe use our camping fridge. Plus not too far from home (Bristol) so we could test out short stays and be close to home in case we need to head back cold and wet! Not asking much eh? 
If we can get in to camping it would be great- DH loves going away for weekends but family rooms in hotels are so expensive, and even holiday homes for a weekend are really expensive these days. Neither of us come from camping families and have both been brought up to be very sceptical about camping!
