Now I'd heard that overnight trains can be a bit hit-as-miss: you share a 4-bed cabin with total snoring strangers, the train speeds along at max speeds of like 300km/h giving you a bit of a bumpy ride and an unsettled sleep, the only escape from this close-encounters of a foreign and slightly awkward kind is the bar, where, you may have to remortgage your home before ordering anything or at least just sit, take photos and talk with random Americans like I did and get drunk with them and not think about the bill so much haha.
Also met one girl who I'd already met in Salou at the Cos Blanco confetti party through a friend of mine. We saw each other at the bar, had a few drinks together and sat talking how small the world is, and how aawesome the experience was, what we were up to and where we were going.
As I wrote all this I was hurtling out of a grey, dull, unpretty Paris at 8am or so after making my connection with about 5 minutes to spare after having to throw my 5 rucksacks around the Paris Metro a bit first.
I then got into Köln Hbf and made my connection there to Koblenz, knocking over my suitcase on poor unsuspecting guys who walked past. Oops.
