I will be taking my 17 year old daughter to Europe in July. Because we were in London already, and because I found incredibly cheap airfare, we decided to spend 3 days in Ireland. My plans are to fly in to Dublin and fly back out of Cork. I would like to take a "slow train" along the Irish coast. Would you suggest a side trip up to Drogheda or a trip to Wexford and then to Cork? Also, does anyone know if a US passport fits the requirement for Ryanairs online checkin (to save a few pounds)? If my passport is due to expire within two weeks of travel, does that break the deal? I tried calling their number - but could never get to a live person and I could never find a way to email my questions to them. Finally, any suggestions in Dublin and Cork to make it more memorable. Thank you for any advice.
