Well, to be honest, I am pretty flexible. I would primarily be in Galway during the periods that I am home but I don't have any problems driving somewhere else. After living in Australia for many years, the driving distances in Ireland just don't seem that big anymore. And I figure, once I am in a plane the distances mean even less.
My main goal would be to rent a plane (localtion flexible), fly to Galway (if not already there) and pick up some people and then just do some general sight seeing. Then drop the plane back same day if necessary or keep overnight / for a few days if possible.
