Hello!
We will be in Ireland for 6 nights the last week in July 2018. Using a rental car to explore Dublin (two nights then rent car) Killarney (2 nights with a day trip Muckroos in the am and a drive out to Ballycarbery Castle in the afternoon), and Kilkenny via Blareny and Rock of Cashel (2 nights). We have a 2:55pm flight from Dublin airport to Zurich.
What time should we arrive at the airport area to drop the car, get to the airport, check one bag and pass security and passport inspections? I have seen that the 'direct' driving route on google maps clocks in at around 90 minutes, but I learned in Scotland to give that a 20% buffer.
Is there enough time/is it worth it to leave Kilkenny early (we will have had a whole day in/around to explore) and pass through Glendalough or some part of the Wicklow area vs going straight to the airport on the motorway?? We like natural beauty, ruined things covered with moss, cute touristy towns with touristy pubs and live music.
