I am flying into Shannon in June and planning on spending 3 nights before flying out of Dublin to go to Amsterdam (no direct flight from SNN to AMS). Is there a reliable train that could get me from that general area to Dublin, if my flight out of Dublin leaves at either 11:45am or 1:45pm?
Or would my best bet be to take the first flight from Shannon to Dublin and have a 4 hour layover at the Dublin airport?
Also, how much would trains be? And can you book them in advance?
Any tips would be greatly appreciated. Thank you!
