We're going for a few days at the end of August so what are the places/ things we shouldn't miss please? We're staying in Chipping Norton.
DC are 12 & 9 so are beyond farms and soft plays. I'm not even sure if I'll be able to coax them into going to Blenheim Palace tbh. I'm looking at the Treasure Trails as that's often the only way I can get DD to put one foot in front of the other. 
Any 'hidden' gems?
