This week, Paddy Haycocks explores the south of Tunisia, from the Mediterranean beaches of Djerba to the desert towns and cave dwellings of the Sahara. Carol Smillie stays closer to home when she visits three Scottish castles - Culzean, Glamis and Stirling. There's a fresh challenge for Matthew Collins and the Travel Show videobox makes its debut.
