We need to get from Paris to Vienna, but I'm having trouble finding cheap airfare (I don't want to spend more than $180 p/person - we are 2). I've been thinking of taking a night train, but I was quoted something like $650+ for a sleeper car. I don't know if I'm looking in the wrong places... Any ideas? Here's part of our itinerary. Maybe you have suggestions on how to get around. We're open to moving things around. The only for-sure is the previous 4 days in the NL. Thanks!
