Hi Nate,
How nice that you are coming over to see us!
While I'm not an Irish speaker, we do have previous threads discussing accurate translations for that same purpose. Here's
one, and
another. Hopefully some of our fluent members will jump in.
Since you really want to make sure the translation is accurate, I would also get in touch with
Foras Na Gaeilge, the organization responsible for the promotion of the Irish language.
Any other souvenirs you got your eyes on or places you wouldn't want to miss on your trip?
Cheers,
Antoine
