We're going to stay near Chippenham in a few weeks to go and see Longleat. However, I'd like a back up wet weather plan, and maybe if there's a few things to do, we could extend our stay.
We've got a National Trust membership if there are any particularly child friendly locations in the area. We've visited everywhere once before, but it was pre-kids, so didn't pay any attention to that side of things!
Would also be interested in any good soft play areas!
