Train
The train travels from Connolly Station in Dublin, to Sligo regularly. Book online for the best prices. The train also stops in Ballymote (Jennifer's hometown, where the ceremony will be held, approx 5-10 minute walk from the station) and Collooney, where the reception is (although quite a distance away from the venue, so maybe best not to plan the train for this section of the day!)
