Shannon or Dublin. We hope to fly over -- heck, we have tickets -- on May 18 and back on June 1. We're flying into Dublin, down south to places like Powerscourt and Glendalough, west over to (roughly) Limerick, down to Dingle (my wife has to visit Ye Olde Familye Stompinge Groundse), over to Cork, up to Belfast, and back down to Dublin. Perhaps not in that exact order.

Fares are horrible. Outrageous. And Ireland isn't a cheap place to visit. PM me for more info.
