Thanks to all your advice, I've decided to only do the southern half instead of the entire country in 12 days. :)
We will be 2 days in Dublin (staying north of the city south of the airport), then 2 days in Galway, 1 day in Doolin, 3 days in Killarney. I'm looking for a place to stay 2 days on our way back to Dublin for our return flight. Last night will be spent as close to the airport as we can (haven't made these reservations yet either...) Any ideas welcome....would like to see Waterford factory, but beyond that, no special plans.
I've heard of people "winging it", but I also realize it is a busy time of year and I'm not sure if I should try that. All other reservations are made...
We leave in 19 days! Hooray! Looking forward to meeting the friendly folks of the Emerald Isle and looking up a few relatives (in the cemeteries...)
