Great idea to plan your train travel for overnight....the coach does double-duty as your hotel room.

Buy food from the grocery stores and make your own meals....the restaurants will bankrupt you soon! Take instant coffee/tea with you and arrange mail shipments of luxury foods from home.

You will get stuff stolen....don't take anything you can't afford to lose. Make sure your group has more than one camera. Don't fall for anyone who says they are an official anything without checking ID carefully.

Don't break any laws and think being a tourist will get you off. Bribery/blackmail in eastern europe will bankrupt you faster than the restaurants.

You'll need a visa to go into Czech Republic, even if just passing through on the train.

Good luck, have fun!
