If you join Caravan Club -quite alot of their sites are near somewhere or even on somewhere like say Longleat, or Burford or Chatsworth, Tredegar near Cardiff, Bristol City Centre, York City Centre, London etc, loads by the coast,their list is literally endless, and they also have affiliated sites in Europe, so every summer we pootled round France. Ok you pay sat £50 a year to join but you know the site will be clean and spacious and have good + clean amenities.
We did it for many years and loved it, stopped last year when ds then 15 got to 6'2" and literally outgrew it.
We used to take our bikes and go off somewhere. Great in France when you can cycle to a patisserie etc

Obviously you have different logistics in your family - but pace of life slows down and it's amazing how you can spend a morning just pottering around in your own doings! and it brought us much closer as a family being lumped together playing cards etc of an evening.
Food, - the last one we had had no oven or microwave, just a 2 burner hob and we did fine on that. We also had a small camping Cadac gas bbq which did a multitude of things. But if it was raining - I can recommend M & S tinned Currys, Chilli and Steak in gravy
- honestly don't knock em till you tried them
We also took it for day trips to motor racing events and when it finished and everyone was queuing out the car park - we be sat eating hot soup with crusty bread and then going home after all of that had died down.
