Have given some answers on your other thread with the Pax House in Dingle and some Ennis links. Killarney we use the Eviston House hotel (upgrade room) or Sunnybank B&B. and Rosquil House is good for Kilkenny. I prefer to be a bit closer to the action and would consider Forge House for Galway, Rusheen Bay is the opposite side of Salthill from Galway and not on a late bus route if you fancy a drink or two.
