airporting - on the way to wild wild east!

Im on the way to XPRO as usual for me the way is long but as cheap as possible :P
So I spent night on Vienna airport- it was raining and cold and flight was delayed so decided to stay at the airport. Eh it is amazingly cool with infrastructure and just the ok place to stay for night, in addition its connected with the center so im going to sighsee vienna on the way back. It is also amazing how the boardes dissappear and how Prague Bratislava and Vienna are almost one in terms of being able just to go from one to naother with the bust or liners etc. But Im on the way to different reality- getting to know that another people have problems with visa- my friends is spoiling my mood about it and happiness :( I dont know why things happen this way, why some people have power to celebrate and so enthusiastically abuse it :( Do not know this answer and would rather not have to ask this questions again:/
