I'm doing a 2 week trip through Europe, and on 2 legs (Berlin ->Vienna and Zurich -> Amsterdam) I was planning on getting a sleeper car.

What does FT think - is it worth it to pay a bit more and have a compartment to myself?

(I'll be staying in hostels the rest of the time, but there's also a sort of camaraderie in hostels that might not be present with random strangers on a train...)

(Sorry if this would be a better thread for Budget Travel, but I thought the people who'd know best would be on this forum - you all seem super knowledgeable)
