I grew up in the days when American Express was the card that you got for travel overseas; after all, that's what American Express originally did! But someone posted a few months ago that her AmEx card wasn't taken (restaurant in Paris, maybe?) because of all the economic and currency trauma.
All my traveling in my Eurailpass and backpack days was with traveler's checks. Ever so long ago!
edit: I did find this, which seems helpful. Since they refer to MasterCard Europe, I'm not sure that our version is handled the same, although I would guess so.
I didn't realize that Republic of Ireland was using the euro now. Seems kind of sad, most of the old national currencies seem to be gone.
