My wife and I are looking at traveling to Ireland from NYC with our 6 month old baby. I would like to take the baby to visit family in Wales (Cardiff area) for a few days since we are so close;-) We are looking at taking the Ferry from Roslare to Pembroke, spend maybe 3 days in Wales then take the ferry back and spend another week or so in different parts of Ireland. I plan to hire a car the entire time. I was just wondering if this makes sense or am I overlooking a better way to do this? Thanks!
