Me and the wife spent 2 weeks there 3 years ago. Flew into Dublin, stayed in the city for 4 days, then went back to the airport, rented a car, and drove around the rest of the country. We went the first week of June, and it was unseasonably warm, in the 90's every day. We stayed one night in the Days inn on talbot street, checked out the next morning, and went up the street to Jury's Parnell Square. We spent a night at Waterford Castle, 2 Nights at the Bianconi in Killorglin, a Night at the Blarney park hotel (which has since burned down), and flew out of Shannon, not in that order. Most other nights we just found a b&b to crash at, after stumbling out of a pub.
