Belfast was relatively peaceful in October when we were there. The signs in the Pubs required us to abstain from talking about politcal and football situations, at least outside of West Belfast. It looks like the situation has deteriorated in the past 4 months.

The Utilikilt was a huge hit in Belfast, people loved the look, and was a great ice breaker. Good luck to you in your journey to Dublin, I'm sure you'll tread lightly.
