I'm not sure exactly what you mean by not much hassle but I'll offer my advice anyway. I'd say book a ticket online if you get the chance around the time you want to come home. That is of course, assuming you can get access to a computer. I'm doing about the same thing - OW into Dub then coming home whenever. I'll have a "base" in Germany though with my in laws so arrangements will be fairly easy. Anyhow, that would be my suggestion for the cheapest ticket - just hop online and book.
