We've got to drive from London to West Wales and the back again early this week and I'm quietly despairing over it. But thinking of sleeping over in Bristol (I've never been) or that sort of area on the way back - close to the M4. Does anyone know a place that would be under £100 (with a firm bed god willing) and handy for a stroll around & something to eat? We'll have our dog in tow so we need to keep it cosy & simple. Thanks in advance.
