Thanks, I looked at intercity.pl and they have tickets for two in a sleeper compartment for approx €176 (€88/person). They told that you can only pick up the tickets at the International Ticket Office. czech-transport.com has same tickets for €136 plus €20 for delivery to hotel. It seems that the best option for me is to get it from czech-transport.com and get them delivered. Or am I missing something. Polrail.com has the tickets as well for €207 and they will send them to me via email. Really appreciate all the good comments and advice. What a great forum
