Daniel,
Great trip and report. Thanks for sharing.
That Christmas market in Ljublijiana looked really festive!
Did you encounter any issues (with authorities) regarding flying drone anywhere?
Was there any airport formality during your international to international transit at SVO?
By coincidence, I have been contemplating a train trip from Northern Italy to Ljubljiana, Zagreb and perhaps Sarajevo. Thanks for doing most of the homework for me! Did you buy all your train tickets online or while you are on location (noted on one occasion you mentioned getting ticket for “tomorrow”)?
