Hi, I will be traveling with my family to Dublin from December 28th - January 2nd. We will be spending most of our time in Dublin, however I would like to take a day trip outside the city. We have some first time travelers to Ireland, so I would really love for them to walk through one of the many castles here. Would a day trip to Cork/Blarney be the best option? I've heard wonderful things about Wicklow & Glendalough, however I'm not sure if that is a better place to visit in warmer months? I would love any suggestions. Thank you!
