Hi, I am travelling around europe in march next year for 3 months and I am going to be travelling by train through about 10 countries so I will be getting a eurail pass. I am travelling with someone else so I can get the 1st class saver pass for about $400 more than 2nd class. I was wondering whether anyone has travelled on both and knows whether this extra $400 is worth it.

Also does anyone know how much it is for a sleeper and a couchette, and whether the reservation for 1st class seats are more than 2nd class reservations?

Thanks for any help
