Dingle peninsula was the highlight when we went there. When my wife and I go back, we may spend a few days in Dingle and around the peninsula.
+1.. Guinness is a tourist trap now more than a tour. You no longer get to tour a working brewery... and it has been turned into a neat tour but.... it is only informative for a person that is new to beer brewing... the memorable part was being able to taste some different types of Guinness on the top floor, but overall it was not as memorable as you would think.
I did not do the distillery, but that is where I would go. ALso, I think Smithwick had a tour as well that we did not hit (lost the coin flip with my wife that day on what we would see lol)
Driving is an absolute experience. If your rent an automatic... be persistant about it. When we went to pick our rental up... they said they did not have anymore automatics and we would have to take a manual.... after 20 or so minutes of not accepting that solution, they did "find one".
I loved driving in Ireland, and I think it is the only way to go. However, it was also the most stressful! The roads are truely narrow and where we in the US have a nice white line to mark the edge of the road... in Ireland they have stone walls that have been in place since 1200 AD... with plant and twigs growing out of them... making the narrow lane even more narrow. LOL Good news is, if your driving... no worries, your spouse will let you know EXACTLY how close you are to the wall at all times, (just know you are not really close until they start to use four letter words... your mileage may vary)
I am looking at my screen background on my computer right now (it has been there ever since we went on our trip three years ago...and I am so enviouse of you right now!!!)
I found that just about any town you go in has a pub... and they all have pretty good beer if you look for it. Most lead with lagers now, but there are still some very nice ales everywhere. If you are lucky, you can get a Guinness and Murphys side by side and have some real fun! We ate at pubs for dinner at night and enjoyed the music whenvever possible. Lunch at the pubs was pretty good to, but sometimes we would grab a take and carry from the gas stations while we drove.
