We did 3 days in Dublin (with a drive south to Glendalough, Wicklow, Powerscourt Estate including several filming locations for Excalibur), then rented a car and drove west. We stayed in Galway and did a 1 day loop up into Joyce Country (Connemara, Clifden, Kylemore Abbey, Cong Abbey) and then a drive to Limerick/Shannon that included The Burren, Cliffs of Moher, Bunratty Castle. So much more to see & do.
