After wandering for a bit (one of my favorite things to do when I get to a new city) we walked down to Kilkenny castle. It was only 2.50 euros with a student ID which I realized right before we paid (Wesley said this was the best clutch move after the Guiness tickets).
The views from the castle were fantastic. There was more live music being played outside on the lawn which we stopped and listened to on our way out.
In Kinsale we decided to stay at the Carlton Hotel.
Getting there was quite interesting. The hotel is nestled far back into the woods kind of off the bath, but it was really cute. It is low season so there aren't too many people making it a quiet place to spend the night.
I'd definitely stay at the Carlton again. Friendly staff, good rates, restaurant and bar, gorgeous views, and of course a pool.
