I wonder if this 59eur price will be as mythical as the advertised Amsterdam-Paris tickets for 39 eur. Whenever I actually want to go for, say, a weekend, it's always something like 300 eur for a roundtrip. For one person. Yes, more expensive than driving, including a day of parking and the highway toll!
Which is extremely sad.
