Thanks to Stewie and Flame3601 for the info. Unfortunately my "like" button seems to have stopped working.
My own plan was CPT, PLZ and a few places in-between for a couple of months around Dec/Jan/Feb.
With what I have read here in mind, I am going to hold off on making any bookings at all. It sounds like it could go any which way. Maybe the country will be closed. Maybe it will be officially open but with domestic restrictions that would destroy the trip. Maybe it'll all be ok by then.
If I do go, it will be a last minute booking. I may, however, be looking to find another warm place to ride out the Austrian winter.
Above all, I send my best wishes to @
Flame3601, family and friends. I really hope things improve for you there soon.
