So far I have booked the following B & B's: Galway (Asgard), Doolin (Roadford) and Dingle (Greenmount House). Any suggestions for Kenmare, Belfast, Dublin?

I had a decent stay at O'Neill's Victorian Pub in Dublin. It is a good location and a great price for Dublin, but it is a bit noisy (being near a busy street and a train). However, it's a true Victorian house with tall ceilings, a pub with food downstairs, and run by three nice brothers.

Anyone have anything to say about Virginias guesthouse in Kenmare or Davitts?

My itinerary now looks like this:
Galway (3 days)
Doolin (1 day)
Dingle (2 days)
Kenmare (2 days)
Kilkenny (1 day)
Belfast ( 2 days)
Dublin (3 days)
I had this new idea and would like some input: I will be leaving Kilkenny early and expect to visit Glendalough and Powerscourt Gardens. Originally I was considering spending the evening near Newgrange so that the following morning we could stop there and then continue on to Belfast, and drive to Giants Causeway the next day. However, my new "idea" is this: After Powerscourt drive directly to the Dublin airport, drop off the car and take the bus to Belfast. Instead of driving to Belfast and to the Giants Causeway we will take a tour bus to the Causeway, take the taxi tour of Belfast and head back to Dublin by train. By doing this I pick up a day and can still see Newgrange (from Dublin) by train, bus or van.
Any comments?

We stayed at Greenmount House and thoroughly enjoyed it. Dingle is most definitely on my list to return to. If you like pubs, look for a poster of Dingle Pubs. Its a great souvenier for us. I'm so happy you're going. Oh,some advise on the maps. We determined red and green lines on a map are much much larger roads than the black lines, which tend to be wide enough for one car. It was just our funny takeawy.
and when you're in a pub, don't hesistate to ask if you can experience 'pulling a Guinness'. It's quite an experience which we enjoyed (not as easy as one would think).

Can anyone suggest places to stay in Belfast and Dublin?

After leaving Kilkenny, driving to both Glendalough and Powerscourt where would you suggest I stay that evening before heading out to Belfast the next morning. I have decided to drive into Belfast and to the Giant Causeway dropping off my rental before heading to Dublin. I will now have 2 days in Belfast and 2 days in Dublin.

Thank you everyone for your help. Except for one night I have everything planned.

As of today we probably won't have time to see Newgrange.
Thanks.

I drive up through Galway everytime I go to Ireland and it's a 2 hour drive maximum from Shannon - maybe 1 hr. 45 min

Can anyone suggest where I should spend the night after leaving Powerscourt? My day starts from Kilkenny driving to Glendalough and then Powerscourt. The next day I will be driving to Belfast. Should I stay near Powerscourt or drive towards Belfast?

Per this website, distance from Shannon to Galway is 52.5 miles and takes about 1 hr 16 mins. This is a good site to get distances and driving times. Be sure to change the default from GB to Ire

GreenDragon already suggested this.

One of the great points that Green Dragon has made is that not everyone can handle so many one and two nighters. We did 24 days in 2006 and three days were perfect lengths to stay anywhere. You got to know your innkeeper, discover and roam the areas and get to meet many locals.We had so much fun getting lost without worrying about checking in or out of our lodging. We also did two four day stays which were great as those areas had so much to offer. After awhile you get sick of unpacking and packing, checkin, checking out. Looks like you have modified your trip a bit to cut down on one nighters. Have fun!!!

We leave in a few days!

Any suggestions for specific places to dine at any of our stops?
Should I purchase euros beforehand in nyc before I arrive in Ireland?
Anything I should know about Aer Lingus?

Thanks!

Here's a link for the latest of many threads on the money question:

As you can see from it, the general consensus here is that it's better to wait until you get there and get Euros from an ATM.

Have a wonderful trip!

I hope you're planning on eating dinner at Roadhouse, we had a wonderful meal there.

Your itinerary still looks a little rushed to me, though as some have said, many don't mind "one nighters"

We spent almost 3 weeks In Ireland last fall, flew into Dublin then did a large circle counter clockwise from near Carlow, south of Dublin. We did Glendalough, Powerscourt ( several other gardens) then a few days in Newgrange area ( loved Monasterboice) west to Burren area, Kylemore, south to Doolin, Cliffs of Moher, then Dingle area, ROK and Kenmare and Killarney National Park, back north to Dublin by Rock of Cashel.

Have you thought of saving Northern Ireland for another trip? Probably too late now,

We loved The Horseshoe Pub in Kenmare

Have a great time, Ireland's amazing!

In Dingle, we had a fantastic meal at a Chinese restaurant called Tir na Ri (Land of the Kings). The owner's last name meant King in Chinese, so it was a pun :)

In Kilkenny, we had wonderful sandwiches at Marble City Cafe, and then went across the alleyway to Dame Kyteler's Inn for pints and traditional music. Caladh was playing that night, and they were fabulous. (we bought a CD)
