Aleckii asked:

I plan to buy a EurailPass 2007, allowing me to travel continuously for 15 days, in order to save time, 4 of the nights we will spend in night trains. But it is stated that we have to pay a supplementary price on a night time (or pay additionally to make reservations), can somebody help me find out what the supplementary charges are?

Also I read that some night trains offer Sleepers, couchettes, sleperetts, etc. A few people have said that it might be uncomfortable to sleep in night trains, is it true? To me and my friends, who are used to taking night trains, we actually find them comfortable.

Anyway, the following are the night trains we are taking, how can we check the supplementary price (on top of the EurailPass 2007)?

EuroNight(EN) Train From Venice to Vienna

DB Nachtzug(NZ) Berlin to Brussels

City NightLine(CNL) Amsterdam to Basel

City NightLine(CNL) Salzburg to Frankfurt
