We will be flying in to Ireland on a cross-Atlantic flight (on coach) and will be arriving in Dublin. We want to proceed immediately to Galway that same day and renting a car is simply not an option due to the fatigue. We have looked into the Citylink coach directly from the Dublin airport to Galway and are thinking about the train as well. Any tips on what would be the best bet for two really tired and probably hungry people? Cheers!
