We had just enough time to take the train from CDG airport to Gare du Nord, find the area where the Aachen train departs, eat ham and cheese omelettes and drink very good coffee at a nice sidewalk cafe outside the station, and have our first Euro sticker-shock when the check arrived.
The train to Aachen was 20 minutes late departing, but we found our reserved seats and are now hurtling thru the French countryside. It's a lovely day - clear, blue sky.
We have been travelling for many hours now, with next to no sleep. However, we are all still reasonably coherent. That could change.
