18 yrs ago, in my single days, I traveled to the Emerald Isle in the company of two single ladies, also teachers. In Dublin, the bars all closed at about 10 or 11 pm. I know, crazy. However, there were secret, underground establishments that were open to all hours that only the locals knew about. We called them the Irish speakeasies.
I'm not sure if this is still the case or not, but if it is, get to know some locals. It's not hard, they love the Yanks. (not the baseball team) Talk about the time of my life! At one point I was dancing in the center of a bevy of Irish beauties on a makeshift dance floor when suddenly the music morphed into a techno/tradition Irish gig. Before I knew it, I was Lord of the Dance!
