Adding to my question of available mini-coach tours, before I go too nuts with all this. Can we be last minute during high season without a car? We are flexible people, so facing the possibility of no tour itinerary perfect, and masses of crowds and buses, would we do well to not plan and make our way to centers, like Killarney, Cork and Galway, and still be able to find housing, plus touring that all the bigger companies ultimately use? Like the Baera and Dingle peninsulas? Otherwise good public bus between areas not served by train? We have two weeks to have everything go slowly or fall apart.
We plan to just do the circle from Dublin, south and west to Galway, finding water viewing, and back to Dublin (unless departing Shannon is that much easier). Not touching the north and Belfast. RS doesn't tour the high season 7/25-8/10, probably for good reason.
