This is our first trip to Ireland. I should also add we are somewhat neophyte European travelers. We land in Dublin at 9 am after an overnight flight out of JFK. We can't check in to our Airbnb until 4 pm. Since we're not using a hotel, there isn't the option to simply ask for our luggage to be held for us. Any other suggestions other than wheeling the dang stuff around with us all day?
Second question: We have five nights booked in Kenmare during which time we plan to explore both the Ring of Kerry and the Dingle Peninsula along with other local sights. We will be driving back to Dublin at the end of our stay in Kenmare with no other overnights planned. If we got up and left Kenmare early is it reasonable to consider first driving north to the Cliffs of Moher and then on to Dublin or is that too much for one day?
