We will be arriving in Dublin on 17/9 at 18.00 pm. We will be in town for 4 nights, leaving on the 21st (Sunday) for Dingle for 3 days, then returning to Dublin to fly to London. So, I was thinking we should buy a round trip 747 ticket, plus a 3 day leap card to start on 18/9. We plan to use public transport in Dublin and out to Malahide/Howth during the three full days we are in Dublin. Can we get a 3-day tourist leap card at the airport that will start the next day (the 18th)? Or can we get a 3 day leap card in town? We will be staying north of the Liffey near Batchelors Walk.
