I am planning a trip to Ireland for next spring and I'm wondering if it is worth it to rent a car for the entire trip, or travel by bus/train and do local rentals? I plan to stay for about 2 weeks, starting in Dublin and visiting Galway area, Cork, Killarney, Dingle, and Waterford (not necessarily in that order).
I would like to do a few day tours, but I'm wondering if it will be easier to have my own transportation for the whole trip, or if I can easily get between cities/towns by train or bus and then rent a car if I want to do more exploration of a local area (will probably be spending a few days in each area).
Any thoughts? Is it more cost effective to travel by train/bus? Or will I save a significant amount of travel time with a rental car (instead of spending time waiting for a bus)?
