Just had to say what a great place this was. It is in Warwick. There is a shopping village which was great. Loads of quaint little shops and things like old fashioned fudge (yummy!) and it was all really cheap.
Then you walk through to Hatton Farm village which was about 7 pounds each (under 2's free) - but well worth it. They had a bouncy castle, birds of prey, lots of different animals, trampolines and loads of interesting lttle diplays. My ds is two and loved the smaller animal like rabbits and sheep. But I think if your children are older they would like the pony rides and panning for pretend gold.
They had a sheep race, and a duck display that was great. They also have a soft play area which you pay a couple of pounds for but ds was too tired! a maze and tractor rides. There was a BBQ and a resturant.
Can really recommend this place, great day out and ample parking.
