Travel series getting under the skin of popular holiday destinations. Today, Joe Lindsay and Emma-Louise Johnston report from one of the world's largest cruise ships. They join the Independence of the Seas with over 4,000 other people as it sails the western Mediterranean, where their ports of call include Sardinia and Lisbon. They give us the low-down on taking a holiday afloat, try surfing and skating on-board, and find out why the myths about cruising being for the elderly only are being blown out of the water. And in 'on your doorstep', we take a short getaway in Co Down to reveal what's on offer in the 'new look' Newcastle.
