I'm sorry, I obviously did not communicate my intentions. What I was looking for from the forum was out of those sites, which in your opinion, could be done in one day and which route would you take. My daughter who will be traveling with us and who has been there before says there are "non-negotiable" sites we must see, but I do not want to spend 18 hours in the car. She says we must see Cliffs of Moher, Ring of Kerry, Galway. I have been told that Kinsale is a "must see" -- so I think you all are right, we cannot see it all. In your opinion, which are the most important for us to see and in what order.
Let me add that we will arrive in Dublin on Tues night late and will Wed, Thurs, Fri & Sat. Our first thought was we would go early Wed morning and drive down the east coast to Kinsale, stay the night and then drive up the west coast and back to Dublin Thursday afternoon.
Thanks for your responses -- I love Rick Steves -- and this forum!
