Dear hikers, thanks to all for useful info and advice. We have accommodation booked at Planika, we'll wait with our decision till Friday, then we'll see... As I say, we have high mountain experience, never walked with ice axe or crampons on snow over 2000m though. Safety first, then our (especially daughter's) wish to conquer Slovenia's highest peak. In school classmates love bragging about the only peak conquered and that's Triglav, they ask why we haven't gone yet despite so many km hiked... Have a nice time and lots of safe pleasant hiking steps I wish. Still glad for any new info.
