My husband and I are flying in to Dublin mid afternoon on April 20th, our son will join us later that evening. We fly out of Dublin on Sunday evening. We are trying to determine the best places to see on such a short trip. The Cliffs of Moher seem to be number 1 on the list. Our son was interested in seeing the Giants Causeway, Northern Ireland. We would very much appreciate any tips, ideas etc. to help us plan out the best sights in a short visit.
