We will be in Maynooth, Ireland for a conference for 6 nights and then we have a week free to explore. We are seasoned travelers having been on many continents but we are 63 now and have never driven on the left side. We love to see small towns but I'm wondering if we should forgo renting a car for safety and comforts sake and maybe take a three day rail or bus tour from Dublin to Cork and Galway. Then also to Wicklow which sounds so lovely. we are nature lovers, and then up to Belfast to the Giants causeway...Any thoughts? How are the rail and bus connections?
