When I went to Ireland, the only choices out and about were instant or stale espresso. A BnB in Wexford had a french press for me, but when I needed a fix elsewhere, I was going the instant route.
That being said, the problem with going on vacation is that you're not home in you controlled microcosm. I drank the instant and bitched about it, but that's one of my favorite pastimes. Wonderful country with wonderful people. Just don't go for the coffee and the rest makes up for it.
