Advice Feedback on 9-Day Itinerary: Dublin, Galway, Doolin, Dingle

Hi, looking for feedback with my revised itinerary: Family of 6 all adults. Car rental is for 2 days. Day 1-3: Dublin, exploring the city and nearby attractions. Day 4-5: Galway, planning to visit Connemara. Day 6: Doolin, aiming for the Cliffs of Moher. Day 7-9: Dingle, with a day trip to the Ring of Kerry. Does this seem too rushed or are we missing any must-see spots? Also, any tips on car rentals and driving in Ireland would be super helpful!
