Day 3 - Take a train or bus to Galway in the morning. Stay in a hotel close to Quay Street. The House Hotel is nice (we stayed there accidentally once). Wander around Galway, including Quay Street, the Cathedral, University College Galway, the Claddagh, Salthill Promenade. Go on a pub crawl in the evening (try and find someone celebrating their 40th birthday and join them)
