Travelling from Staffordshire to South London tomorrow with 1 and 4 yo DDs. Journey up yesterday was sheer hell so want to make the return leg nicer. Ideally we’d like a free play park with a few picnic benches and a supermarket between motorway and it to grab a picnic (staying with mil so bringing our own sarnies from her is too difficult). We really don’t want to stray far from the motorway. Any suggestions? I’ve spotted the spiceball country park in Banbury.....
