Do you have an idea how much it would cost? Could not find it on th website...
Around 55zl. 85-ish for first class. The ones with IR (rather than TLK)over the picture of the train are a little cheaper, but there isn't much difference.
Aaaaand, I dont have to book before right? Would i have any disadvanteges just booking a couple hours before the train leaves?
No. You wouldn't have a problem.
