We were in a sleeper car for the aforementioned overnight train. I’d never been in a sleeper car compartment before, they’re very “cozy” with six bunks in a very small volume. Once you’re asleep, it doesn’t really matter anyways. And they even give you sheets and a blanket and a pillow.
And on top of that, we arrived bright and early at 6:15am local time, so now we have the whole day to explore Munich!
