Why Slovenia? Why Ljubljana?
Look at a map... find Udine in Italy where Cloanto is located and where one of the other shows is held - look how far away it is to Ljubljana? Two hours on the train - tops, and most of that time will probably be spendt on the border crossing :-)
Anyways, Slovenia is a nice country to visit, Ljubljana is indeed a nice town, really likeable :-D
For anyone living in south central europe, most of the OS4 tour shows are just a few hours with the train away.
