Kim (and Robert), I am the one that has posted re: Tony many times.
I do not think Tony still has his taxi/driver business. He was fabulous when we hired him, but that was, gosh, 9 or 10 years ago. I have tried to email him a few times over the last year, when I would receive RSForum private messages asking about him, but the email always bounces back as undeliverable. I do not have international calling, so I have not tried by phone. If someone reaches him and finds out he is still driving for hire, please let me know.
My recommendation would be to ask some of your B&Bs and hotels for recommendations for a driver -- that is how we found Tony at the time.
It would definitely be good to have a local driver (especially if you are in a fair-sized vehicle) going thru Conor Pass (which is incredibly beautiful and a must-see in my book).
You asked about Galway. We stopped there for a quick lunch and then spent some time going thru several of the really cute shops and seeing street performers on (I believe the name was Key Street), then on our way to Ashford Castle. You will truly enjoy Ashford. If the web site does not show a 2-night special for when you plan to stay, definitely call to see if you can arrange one. It was incredible when we were there, but ownership has since changed and a lovely update was done to the castle, along with the addition of Irish Wolfhounds. The hawk walk was definitely a highlight.
We stayed in Bunratty our last night, as our flight home was from Shannon. We did not attend the banquet, but walked thru the folk park (and my Irish cousin told me it was as close to what it might be like for when my grandmother was growing up in Ireland). We enjoyed it, and there were two pub-type restaurants just outside the grounds, and we conveniently dined there our last night.
For nights where you are staying put (for 2 or more nights), you can also piece together a series of drivers, or take the train for part and then hire a driver for other times. We used Tony for initial airport pickup, thru Adare, then on to the Rock of Cashel, then on to Kinsale (where we overnighted...and is a lovely sea-side city.....Tony handled his own expenses), then the next morning we drove along the coast with stops along the way, then lunch in Kenmare, the Muckross House (or vice versa..do not recall the order), then on to Dromoland Castle (for a two-night stay). Tony went on home to Doolin to take other fares, then he picked us up the morning we were ready to go, dropped us at the Cliffs to visit, while he took our luggage to the B&B in Doolin, then we had someone simply call him when we were ready go to to our B&B. That night we dined at a pub in Doolin, a simple 2-minute walk down the hill from our B&B, then the next morning he met us to go thru The Buren, lunch stop in Galway, then on up thru the Connemera (which is lovely on Sky Road, and listed in National Geographic's 500 Journeys of a Lifetime book, then he dropped us off at Ashford Castle (as I told him I wanted to arrive there before dark). Had we had more time, I would have like to visit Kylemore Abbey, but we saw it from the road. Then we paid him and said our good-byes. Then after a two-night stay, my cousin (who I was meeting for the first time) took us to see the cottage in which my grandmother was born, other family sites (and we stayed at a B&B in Tubbercurry where the owner amazingly helped me to originally connect with my cousin.....her daughter, it turned out, taught his grandson in a local school...small world), and there we pre-hired a local driver to take us to Shannon (even though my cousin tried to insist...it would have been a really long day for her...so we arrived with it all pre-arranged).
We did not visit Dublin, but I would definitely check into the train, if we were arriving there then heading south.
Enjoy Ireland. It is a wonderful place, and we hope to get back someday for many reason. Safe and fun travels!!
