i was 'bout to say, "you don't have to do all of Europe in a week". hehehehe. ya man spread it out over years. 1 city/day isn't the way to go, but that's just my opinion.
My favourite places for a break would be Edinburgh/Barcelona/West coast of France/Amsterdam/Bavaria/Reykjavik
but nothing beats a lap of Ireland when you've got the weather with you
I'm from Ireland but more importantly I'm from Cork...
