We leave for Ireland in 14 days! We will have to pack early because we are leaving the day after we get married. I would like some packing advice since this is our first trip to Ireland. Most of the weather and travel sites say the temp in early October is 50-60. Should we pack a light coat or will a heavier coat be better? Is rain gear needed? Any must haves while traveling? We will be in Dublin for a few days then in Killarney for 5 days. We will be traveling by train. Thanks for any advice.
