Yeah should be cool dude!!

Logistics were also the major issue here, but it seems to be working out

The thing is that the previous weekend I will be in London for another event.
I will have to decide if I will return to Athens and go to Krakow or go there straight from London, which I will probably do.
Do you know any means of transportation ( bus, train etc ) that is cheap and can get me to Krakow ?
