owenc does have a point though. Read any travel forum on the island of Ireland and 50% of them are interested in doing the exact same tour that starts in Dublin, goes to Kilkenny, Killarney, the Cliffs of Moher and Galway before flying out of Shannon (or the opposite way around).
What that actually shows though is that there is great potential for growth on the island as there are loads of areas that work for European tourists that the Americans scarcely see.
