If I were you I would arrive in Dublin and depart from Shannon...
Missing Kerry is a tough decision... Ballybunon, Lahinch in Clare, Tralee in Kerry.
Asides from the golf, Kerry is the heart of Ireland to me. It offers the scenery and culture that non golfers will enjoy (if traveling with family etc)
I agree. Kerry is a great spot. Played Ballybunnion 2 years ago and it was phenominal. So much to do down there. I've been through most of Ireland a couple of times and the Southwest is my favorite
