Got it! Well, it sounds really cool. I've had luck with both trains and budget airlines in Europe - usually it's just a matter of which is cheaper and/or more convenient at the time, and it seems to be split pretty equally.
I do think trains are much more eco-friendly, though, and the experience is so much nicer... there's nothing quite like rolling through sunflower fields in France, rolling green hills in Ireland, or the beautiful rocky sea coast in Denmark....
