Thanks for the info!

We took the Citilink bus from DUB to Galway. I bought the tickets in advance online to save time. The start of this video helped as by the time we arrived in Dublin we had been awake for almost 24 hours.

It was all very easy and we got through so quickly we entered up taking an earlier bus.
