DH will be 83 next year, so a rental car is likely moot. My thinking is to head to either Ennis or Limerick via train or bus after landing at DUB and take day trips from there- the Cliffs of Moher is a definite. It would only be for 2 or 3 nights. Galway isn"t an option, because we've explored it and the area north of there extensively by car including a cruise to the Aran Islands.
Looking for pros/cons of having either Ennis or Limerick as a base for day tours, thanks!
