My OP on this was intended to draw attention to the discord between the need to attract tourists and the lack of facilities for them. I don't know if it the same in other airports in Ireland. However, I doubt very much that, for example, Barcelona, which might be seen as the second airport in Spain, has signs only in Spanish and Catalan.....
Of course people should be able to manage, but some help would be welcome. BTW, the people concerned had never visited an English speaking country before. They enjoyed their stay... despite the poor start.
