I went to that part around 15 years ago with my then-girlfriend who had family in Slovenia. It was such an amazing experience. Your post about Bled made me go back there, but I forgot to comment, so here's my "thanks for bringing back memories!"

Back then, we did a two day trip to Venice by train. That was quite the experience, as the train station in Slovenia didn't have any time tables, and the station guard was like "It arrives some time between 3 and 4pm." Venice was quite the experience, too. I was told it changed a lot since then, yet again.
