Travel series getting under the skin of popular holiday destinations. Joe Lindsay and Emma-Louise Johnston report from Abu Dhabi, a rising star of the Middle Eastern tourist trade, which is giving nearby rival Dubai a run for its money. From their base at the iconic Yas Hotel, which uniquely straddles the Formula 1 Grand Prix circuit, they visit one of the world's largest and most opulent mosques, and the extravagant Emirates Palace which cost nearly two billion pounds to build. Plus, there's a look at Ireland's party city of Galway and the new daily flight connection between Galway and Belfast.
