Today's destination is Britain's favourite seaside resort - Blackpool. Miriam Margolyes leads a trip around beautiful beaches, fun-packed piers and to the top of the iconic Blackpool Tower. We meet fearsome landladies and indomitable pensioners, take a twirl around the floor of the historic Tower Ballroom, learn how Blackpool rock is made and see behind the scenes of the famous illuminations in a wonderful whistle-stop tour.
