For my trip from Galway to Dublin, I booked the Expressway service from Bus Eireann and was highly disappointed. The trip was advertised to run from 10:30AM and arriving in Dublin at 1PM. I did not arrive until 2:45PM and had to cancel some activities. I contacted Bus Eireann customer service about this issue, and they still haven't responded. On top of that, the seats are uncomfortable and the drive is not as scenic as the train.
