Going to Portugal in a few weeks. We fly into Dublin with a 2 1/2 layover for our connecting flight. I've read that if your flight is between 4am to 4pm and in the same terminal with no checked bags you don't have to go through Ireland customs. Anybody know anything about this airport and if that's true. Also, we fly back to Dublin after 6 days and staying in the city for another 5. Any Aggie bars in Dublin?
