Personally gents, I would pile the kids into the car and drive the Northumberland Coastal Route; go through Beadnell, Craster etc for some good fresh air and some great views. Stop off at Seahouses for a whale end and chips (£3.50 per portion, economic and wholesome) then maybe finish off with a visit to Holy Island. A nice day out, a bit of fresh air, great history and some good bait. Spot on.
