Romantic getaway

My boyfriend and I live very far apart, and it's difficult for us to see each other often. I know that's a classic sob story, but there it is. I'm a student and he's very underpaid in a part time job, so we really can't afford much. We'd both really love to have a little mini holiday in Dublin to see a show and stay in a hotel, just to relax and forget the distance between us. It would be amazing if you could help us out.
