We are two Seattle couples in our late sixties and early seventies planning to visit Ireland for the first time in September.  We think we want to avoid driving.  Our interests center on the Dingle Peninsula, the Ring of Kerry, and perhaps the Aran Islands.  We haven't settled on lodgings; we may be interested in renting a vacation home for a week in a location convenient to those areas.  Would Killarney be a good place to base ourselves?  Can anybody suggest a car and driver/guide?  If we flew into Cork, what would be the best way to get to Killarney?  Thank you.
