Dingle, Galway, or Cork???

I will be in Ireland for six days in June. Will spend two nights in Dublin to get over the jet lag then I want to pick basically just one area to spend 4 nights and really enjoy it. I don't want to try to stretch myself too thin by visiting too much in too short a time so I have to pick just one area. Will be with my 8 year old son. We are interested in casual history, beautiful scenery, food, traditional pubs and music. What area do you think would be the best for us? We will rent a car. I want Dingle, my son wants Galway, and my husband wants Cork ha. Thank you!
